When I was in college, I liked a girl. One day I asked her out for movie. To my surprise, immediately she said no problem and told me the theater and the name of the movie, of course the date and time to meet. That night I went there. She was there but with her roommate, a younger girl. Then she told me she already bought 3 tickets. Man, what can I do? I can not say no, went in, watched the movie and sent them back to the dorm...
Since WQ is married with children, that's even easier. Say yes to him and tell him you will bring your kids. So he has to bring his kids. And it must be a family friendly place. If necessary, throw in your LD and his LD. And make sure you pay the bill, seriously.
