How do you want people to remember you?

I would like to be remembered as striving to do the right thing, being kind, and a loyal friend.

If you could spend a week anywhere in the world, where would it be and why?

With a great group of friends, anywhere, because we’d make the very best of it. By the beach, with a breeze and some sun, is optimal though.
