I've found over the years that I don't make much effort to keep relationships that dont pertain to really close friends. Im always afraid that they have just forgotten about me and it will be weird if I say hi. Even this past year, there was a girl who would say hi to me in the hallway, but if she didn't I wouldn't say it back, so we stopped talking altogether. Its happened other times too, thats just the most recent. Does anyone else deal with this and know some solutions?
