alt Hacker NewsI like this poster thing. Anything that gives people a little connection to those around them.
I sometimes sit on my front step and play guitar. 9/10 people ignore me but usually I'll have one or two nice conversations with a neighbor, and have made a couple friends this way. It helps that I live in a dense walkable place with lots of people who are similar to me.
I've done sidewalk art with my kid. Between Spring and Fall last year, I'd make a new drawing every time it rained. Rarely was there a day without chalk on my sidewalk.
I did it to play with my kid (and learn a little Japanese by writing the title in kanji), but another outcome was talking to neighbors. I keep to myself and have been told I'm difficult to approach, but people often come up and compliment the drawings. One lady said that, when walking with her granddaughter, she makes sure to see what's new on my sidewalk. It's been a very "low risk" way to put myself out there. I draw without anyone looking, and chatty people come to me while I'm in the yard.
