AITA for refusing to fix my neighbor’s laptop for free after he told everyone in the building I’m the neighborhood IT guy? I’m a software engineer, and I work from home. My neighbor, an older guy who lives two floors down, asked me a few months ago for help setting up his printer. It took me ten minutes, and I didn't mind doing a neighborly favor. The problem is that he apparently went on a crusade telling everyone in our 20-unit building that I’m a tech genius who helps everyone for free. Sudd
