My wife's acquaintance (they used to be friends) from High School is going to be upset to learn that she's wasted all that time on her PhD in 17th century French Architecture. She's 33 and almost finished, I believe she's still working as a barista.

I can't even type that out without thinking of this scene from Groundhog Day but seriously.....

Phil: [laughs] What a waste of time! I mean, for someone else that would be an incredible waste of time. It's so bold of you to choose that. It's incredible; you must have been a very very strong person.
