I had this situation once as a teenager and it was extremely awkward because the other guy asked me an actual question and I didn’t understand anything and also not that it was a question and I just smiled. He looked at me like I was insane or something and I was so embarrassed I didn’t even say anything about it. Thankfully it wasn’t important or so but it kind of burned me for life so much that I now always rather ask 2-3 times if I didn’t understand anything before answering. I think this helped, overall. It’s really important to understand something before answering or emoting. ;) Asking to repeat something is not a problem at all.
