If you could have dinner with three people alive or dead?

Bon Scott
Ronnie James Dio
Lemmy

Hands down My Grandmother. Miss her more than words.
My birth mother since that would mean I finally found her.
and for the third, honestly my adoptive mom but in a healthy state. She had a massive stroke when I was 13 and was ill for years before that so I really don't remember her "before" the brain trauma.

There's a lot of famous people I would like to meet but I think those 3 would be more meaningful to me

My grandfather, he passed away 2010 but he raised me and I would love to have another dinner with him.
Julius Caesar
Richard Feynman

John Wayne
Ronald Reagan
Barry Obama

With me there, I think Barry will Have three people willing to challenge his stance on a variety of issues. Could be fun!
I can here Reagan laugh and say, "there he goes again! You can tell he is lying because his ears stick out."
John Wayne will stand over him and impress on him that the leader of the greatest country in the world, does not bow or apologize to anyone, and we don't rename terrorism to be called demonstrations or workplace violence. What we do is announce to the world that when we find a terrorist we will eliminate the scumbag in any means we can.
Then Ron will remind him that the greatest democrat in history lowered taxes, and in a famous speech said to his countrymen, "ask not what your country can do for you, but what you can do for your country".
