Yay! It seems like I always read on here about people's crabby/unhelpful assistants. (Like the posts before admin assistant day) I'm glad you have a good one!
My mom is actually still incredibly close to her past assistants, and best friends with her first real assistant as an executive. She is like an aunt to me. It is a rare boss that treats their assistant as well as they should be, and it's awesome that you appreciate her like that. It pays off!
