Can I be only really be impressed with his skills?
I can understand that but do you think you should go out with him? He seems to have a lot of good qualities.
I don't think it will be a good idea if I go out with him.
It is a good idea to date people that seem like good people. It will help you meet people and grow your network of friends. There is no harm in going on a date, you do not have to get married!
No, I am begging you. No, I don't want to date him.
Are you sure? It is always nice to give nice people a chance at a relationship, although at the end of the day it is entirely your call.
