Even if it's not received well. I spent most of my life feeling awkward around other people (and still sometimes do) but I love chatting it up with a stranger. Giving a compliment, cracking a joke. An internet acquaintance is in Boston? Let's go get a drink! Making friends this way proves something to a younger, more shy version of myself.
Smiled and said hello to Bimh who works at the post office earlier because last week we had a nice conversation.
