My wife and kids are constantly pushing me to call my friends and arrange hangouts with them. It is not that I am anti-social or particularly introverted.

I genuinely love my friends and love it when I hang out with them - however I just always seem to be busy doing stuff and never really realise that I haven't called any of them for many weeks. It is just not in my nature to reach out randomly to see if someone wants to hang out.

I think a lot of it is to do with how I was raised - I think it was ingrained in my psyche that it was 'rude' to call upon people and better to wait until they called you. To reach out was seeing a impolite or possibly interrupting their important work, I think. Funny how those little beliefs/lessons when you are a kid tends to follow you into adulthood.
