Today in psychology class we discussed how relationships work. This wasn't very easy for me because I have never been in one. If you talk to someone that is in a relationship, they are all "oh relationships aren't that great, they're really overrated." Well that might be true if you see it that way, but if all someone wants is just someone they can talk to in a more intimate setting, then relationships aren't overrated.
They are very important for retaining someone's sanity. If there is someone that you share everything with, everything will be much easier to deal with.
