A classmate that I don't know at university asked me if they could take pictures from the lessons (my notebook). I didn't say anything at all and just handed her the notebook and at the end when she said thank you I said your welcome. I thought the not saying anything part was awkward almost like I'm ignoring her.
I'm kind of terrible at social skills and it's mostly because I don't know how to respond, so I thought it's better if everytime I thought I made a mistake I ask others so I can memorise the respond for later if it happened.
