The Cable Guy..

I have a first date tomorrow afternoon with the Cable Guy.  We are just meeting for a drink.  What I like most about him is he has a great sense of humor.  He is understanding my sarcasm, and has witty comebacks.  His profile reads he is a widower, and I don't plan on asking him the story.  I believe this would be disrespectful.  I don't believe in talking about exes on dates, but does this go for exes whom have passed away?  This is going to be an interesting date.
