It's just something that happened
I went to the dentist when my mom's health was declining - a couple months before she died - and I was greeted with the usual small talk, which I normally participate in, but I just wasn't up for it on that day. I could have faked my way through it. I wasn't distraught. I was capable of politely answering his questions, but that would have made it worse. Pretending not to feel the way I was actually feeling would have been disrespectful to the way I was feeling. Or at least that's how it felt to me at the time. So I didn't try, and it made the appointment very awkward. The dentist clearly didn't know what to make of the way I was acting. I could have explained myself, but I didn't feel like doing that either.
I don't really have a point. It's just something that happened.
