sometimes I wish I had a normal job and I'd walk into a building and say good morning to a dozen people I just knew from work etc instead of staying in working on my things by myself day in day out but then I remember I've done "normal" before and it bores me to no end and that the way things are now are challenging but they're just part of why it's so worth it. but still, from time to time...
maybe you could join a good morning club. just go there and say good morning to everyone and then leave
