Can't get it right

My dad recently moved down the road after getting divorced. It's the first time since I've been married that family is nearby. Been married 13 years, have a teenaged son, son in kindergarten, and baby daughter.I asked my dad to watch my middle child so my wife and I could go out for the first time in 13 years almost kidless to a dinner.He said yes. My wife reminded me his big dog bit the neighbor last month so I asked if the dog would be a problem.Rather then assure me everything would be ok, he seems to have taken offense and said he won't watch his Grand son.This is why I tiptoe around when talking with my dad, everything sets him off.This is why I never have my kids go anywhere without us. It's like it's a problem to have worries about safety.I'm just annoyed, sorry.Convo:Me: Can you watch [kid name] for a few hours tonightDad: Yes I canMe: Would be at like 5 or 6 I'm guessingDad: OK just let me knowMe: [Dog name] won't bite [kid name] rightDad: Has [dog name] bitten beforeMe: The neighbor guyDad: No I mean [kid name]Me: I don't think so. I just worry about my kids is allDad: Yeah you're right, maybe I shouldn't babysit himMe: Oh. Ok then via /r/Parenting https://ift.tt/2Pq50kF
