I don't think I could stand a puppy pad, it might be a good alternative but I just wouldn't want it in the house. lol My little boxer pup is only 7 months but she is getting to the point to where she wines when she wants out. Which is good, but sometimes she gets too preoccupied with something and forgets to let me know. Oops accident >.<
About my thread though I think you're right. My sister already has issues with my Dad and I don't want to come off as a father figure. Though I have done like you said and I always get "I don't want to talk about it" So I just always try to go out and do things with her, even if its little things.
