Whats the problem with just talking

so i spent the day with my friend yesterday. i got up early and went to church with her roommate then we met up with her at taco bell and grabbed lunch. after that we came back and i went rollerblading for a little bit then went back to my friends apartment and hung out with her til i went home. on the way to taco bell her roomate was complaining to me about how she has to work and my friend doesn't have to work and that she should. she was also saying how she doesn't get how my friend's parents don't make her work. while she kept venting i just sat there and listened and told her that maybe she shouls talk to my friend about it.
Later on in the day when i was hanging out with my friend she starts telling me about how her roomate complains all the time about how she has to work and how my friend doesn't and then my friend decided to vent all her frustration out about the exact same thing. i had to laugh because it was funny to me that both of them are upset about something that is totally a personal choice that they made. i told my friend to talk about it but she also said no.
My Thoughts?
first of all they have a choice weather or not they choose to work or not work, safe or not safe, Money is a personal choice and they need to stop getting upset because of what the other chosses. it was ridiculous. Secondly why couldn't they just talk about it. it is evident that they both have a different perspective on it and they both are justifiable so why not just learn the other person's perspective instead of getting upset over it.
thirdly, as i was just writing this i wonder if i have ever gotten upset over something stupid like this?
k i got to go return my books and see if i can make any money so i can go to encounter tommorrow.
