Mr. Jennings, the answer is

 Bread and Butter.

The Queens expensive black handbag holds a Bread-and-Butter sandwich for later just in case her car breaks down and she misses supper.

Or perhaps a nice piece of British cheese might have left out on the sideboard. 

I'm sure it started in her days of changes ambulance tires, having to get up early and before staff was ready to serve the King much less a lowly princess.

She would have to make do with what was available in the kitchen, no marmalade that was for tea and locked in the butlers pantry. It would have been just bread and butter. 

I wonder do you think she boiled herself a pot of tea before she left? Or waited with a headache until she arrived at her destination for the Ambulance company of which she worked?

Anyways she reveals her secret to your favorite childhood friend Mr. Paddington Bear. They are having tea while the party outside is beginning with the young ones enjoying the music.

At least the young ones of her family, the grandchildren and theirs appeared to incredibly bored. 

Really, Mic Jagar! and Who were those other old rock stars with guitars. Bring on some modern Punkies or is it a different style now that I don't have grandchildren?

Well, Mr. Paddington revealed he had a sandwich in his hat while she poured his tea, playing the part of mum, and then revealed that she keeps hers in her purse.

There are a few differences in having a bear over for tea after all. A hat really, all those nice expensive ones she has would get ruined. 

It was a delightful comedy sketch with butler appearing, for her grandchildren presumably. 

Meanwhile, The greatgrandchildren looked quite miserable sitting between mum and dad, Kate and William.

William got to get up and do his bit for the environment and it was a very nice speech. 

Harry did not get anything at all for marrying the wrong girl.

Imagine bringing home a mafia girlster.

Really, everyone in Hollywood knows she is Connie Sellecas missing newborn from the Manhattan hospital. 

Mafia mama, who could do no wrong and suddenly got hers stolen and then a divorced.

Only to return to sunny California where she watched the little bitch raised and do nothing at all except waltz into a million dollar contract.

Wonder who the real dada is? Epstein? Now long gone by hanging? Or some other mafia type figure.

It is certainly not the man who just had a stroke and she is refusing to go see in the hospital.

Instead, she came back to the country she had disowned to throw a one-year-old party for her Lilibet white skinned daughter on the Queens day. 

Well, I wouldn't let her near my children or grandchildren, the stories about her and that wicked little finger of hers rivals that of the young Demis, another thugster girl who arrived by night and took over everyone's Elses show.

There was a nice tribute by the not so young Prince Charles, addressing her as Mummy. It was quite charming the country throwing a bash for her and her allowing her family to enjoy it while she sat and mourned her not so long ago dead husband her was so much part of her life.

But the tribute went off wonderfully and todays pageantry is probably going to be the best ever, if the local news will just cover it on a Sunday morning.

I bet the Queen as a Princess could not only change a tire for her ambulance, but also make a spot of tea for her papa the King.

I assume that one of the reasons she got up early was to attend war planning meetings with him or to go to special courses taught by handsome young military types such as the one she married.

She was just up and about driving herself as usual not to long ago. But this long pandemic has gotten her in her legs and back, mobility issues of walking and stepping up are now an issue without her still handsome husband there to attend to her needs.

Imagine the life she would have had if she had not become Queen, a moviestar life such as her sister? She certainly attracted the mafia type on her trip to California and Hollywood, which my own grandmother sent home from London claimed was nothing more than a charlatan.

Everyone claiming to come from royalty or some foreign counrty when really they appeared to all be on the run from bank robberies or mental institutions. 

But she did her job introducing the Second war crowd as she had dodging the London blitzes just before that. 

And then they put her out to retire already to old and not even thirty.
