Not inconsiderate.
Mrs Schreds goes to movies all the time with her dad. This is a win/win for me. First, I don't have to spend time around my F-I-L who annoys the eff out of me (see socially awkward situs thread). Second, I don't have to go sit by some bad person (probably my F-I-L) who's chomping his damn popcorn for 1 1/2 hours watching a movie I don't want to see in the first place. If it's a movie I want to watch, I just wait till it comes out on demand or Netflix and she can watch it again with me if she chooses to.
