Date men from United States / California / Paso Robles, 48 year old

Date someone special from United States. I'm looking for someone with a great laugh and uses it often (and appropriately. I like someone who can hold up her end of the conversation, who is willing to help and to be helped in that project of problem. It's a partnership. I have a good intellect and some strong opinions. I don't care if you agree with me as long as we can discuss things without taking it personally. If we always agreed on things, how would that broaden us? Can you take it if I throw out a quick quip or a bad pun? But then with a pun, sometimes bad is good?
I like to have a little fun on the weekends so I can stay serious at work. I work in the health care field, so sometimes my humor is a bit dark (it's a defense mechanism).
I have a big heart and will go out of my way to avoid stepping on your toes.
