The guy was talking about osteoarthritis or something. He was a neurosurgeon and apparently the subject was joint diseases and some other things. I was at a birthday party of my cousin and after a few sentences I made my way out of here as I was not interested at all. The guy could be funny at occasions but whenever he spoke about work it became quite boring for me. The good thing is that there were many more people at the party and a few cousins were there who I had not seen for a long time, so we had plenty of things to talk about. It was a very nice day in the end and I will try to stay in touch.
