Only places I can sit and eat alone without feeling weird is eating lunch on a workday. Because it just comes off as getting a quick bite to eat out of convenience and go. But lunch or dinner on a non work day or weekend, that's when I feel weird doing so, because that is when one is suppose to only do this when you're with people. Although with me, if I am in the situation where I am eating alone, I will just cook and eat at home. It's cheaper and there really isn't much of an incentive to go out and eat if I am not with people anyways. For people who don't know how to cook or are too lazy to, I can see why.
Enjoy any good things, even the little and menial ones, as you will never know what impending distresses could descend upon you in a moment.
If I fail to adapt to the fault of others, it is my fault.
