By the way, Пока means 'Bye'.
Okay, now I'm REALLY going to go. You should too, missy.
As for your grandfather, just be happy you have him for a while. I love hearing my grandfather's stories about the old country and things in his childhood.
I can't get my old job back and I don't have a car (or need one, since I'm leaving for Boston in a year and a few months), so other jobs would be out of the question because I wouldn't be able to work regular hours.
And my grandfather like my mother, believes that I'm almost considered an adult in American society, so I should start taking responsibility and learn what's worth money and what isn't.
