Come on, Hostess

MK went out with a couple of girlfriends to catch up and have dinner. I thought it might be a neat idea to surprise MK at the restaurant. I called up and spoke with the hostess and told her a short version of what I was doing for my wife and asked if she would help me out. She was all aboard and really into the idea. She was going to have MK's waiter go by the table and single MK out and let her know that there was a guy who thought she was very beautiful. Then after a brief second let her know the guys name was Cotie. So MK came home after her dinner and talked about her time out with the girls. I asked her if anything happened at the table and she said nothing special. Then I told her what was supposed to happen. She said it was ok because it probably would have been uncomfortable for a stranger to do that and that the thought and effort was plenty enough.

Question. Why does romance or doing something "sweet" have to be uncomfortable?
