i'm very bad at eye contact, but in high school i worked really hard to not just stare at the floor all the time so i can do it now, even though it's still uncomfortable etc...nobody has said anything about it to me lately.
and actually i find that when i do try to make eye contact, other people tend to look away a lot. i'm not sure if this means i'm doing it too much or if that's how eye contact usually goes with people. sometimes i just keep looking but other times i will also look away when i see them look away and then look back, look away, etc. i still need to do more experiments before i develop a sound theory.
