I had an anger problem when I was younger. Had that happen at a party with an acquaintance that ran in our circle of friends. Took a personal bag of chips like that, the dollar bag. The worst part was his smug smile while he ate a chip. Snatched em out of his hand crushed em and dumped the bag on his head. Damn near got in a fight over it. Id say your reaction was better than mine, but you also don’t want to let yourself be a doormat. Thankfully I’ve calmed down a lot since those days, but I also surround myself with better people now as well. Somewhere between our reactions is where you’d want to be.
