This works wonders. I did it accidentally. In March 2020 when my gym closed, I started working out every night in the garage. After a couple of weeks a neighbor who I only ever said "hi" to wondered by and asked if he could join since his gym was closed. After a while more showed up, and now I have like 12 people every day show up. One Friday someone brought a bottle of whiskey and we hung out after the workout and now weekly happy hours are a regular occurrence. The neighbors who don't workout stop by after the workout for happy hour. It's almost become expected and folks schedule their weeks around it so that they can be there for drinks in the evening. As a super introvert nerd, I never thought I'd be the center of community in my neighborhood.
