What seemingly polite or enthusiastic behaviors at social gatherings do you secretly hate?

A few weeks ago, I went to a family gathering, and out of nowhere, someone suggested I take a group photo with the relatives. Normally, this wouldn't be a big deal, but then they started insisting that I smile for the camera, telling me how 'great' I'd look if I just gave a big grin. The pressure was so intense—everyone was staring, encouraging me, saying things like 'Come on, just smile!' I felt trapped, like I couldn't escape the situation without being rude. Eventually, I forced a smile, but inside, I felt uncomfortable and overwhelmed. This kind of 'enthusiastic encouragement' feels more like pressure than positivity. I still feel uneasy just thinking about it.

What about you? Are there any seemingly polite or well-meaning behaviors at social events that make you cringe or feel uncomfortable?
