I think it’s safe to say that Thomas has a habit of underestimating people. Or at the very least expecting the worst from them. It’s probably safe to say that every person in the store is aware that Thomas & Carol have feelings for each other even if they don’t know the exact status of their relationship. Even self absorbed Reggie can see flirting for what it is. Most people can spot it when others do it even when they can’t tell when they are being flirted with. A little distance really helps.
Speaking of things that help, it helps me when people support my work via Patreon or other options in the links above. If you can spare something, even in these trying times, to show you are enjoying my efforts I would appreciate it. If not, well, I get it. Things are tough all over.
