Both my parents tried university but dropped after a year. However they have always highly valued education for me, probably because they didn't really have one. They are the ones pushing me to try for a Ph.D. While its great to be supported, they do not know much about academia and it can get really furstrating. They have no idea how hard it actually is. When I got my BA , they barely congratulated me because to them there was no way I would not have it. Same for my Masters. They think its like high school you do the bare minimum and you're good.
If you look at my extended family, a lot of them work in factories or rural area and criticized me for wasting my time at university.
