How many teenager's father's walk around their house wearing nothing but a towel? With a thirteen year old daughter alone with him?

I don't know a lot of thirteen year olds right now but I never knew dads like that. Maybe he feels okay with it around you because your family and/or home is where he believes he can do things like that because he feels secure there and/or he is your general weirdo. It could be a general male thing like, "I can do whatever I want because I am a man!". In other words, lazy.

Does he do it when your mother is at home? If not, talk about it with your mother because some dads get angry. Why? Because in their mind, it's logical to get mad at this because you're being disrespectful and this and that and blah blah blah.

If your dad is not a creeper or a mean dude, then ask him not to do that around you in a sort of scared child manner. Say you are really uncomfortable about it. Remember to say it nicely and not accusatory or in a negative manner. Say it with confusion. That usually works when my stubborn dad won't listen to me.

If both parents are unreasonable and won't be able to understand that you want him to stop walking around the house in only a towel, you're going to have to deal with it. Sorry but just ignore it and everything else, because there'll be more later on.  I know it sounds unfair but you're going to have to be the best of what humanity has to offer while your parents are not. Just concentrate on college, financial stability, and friends. Live a happy life. Peace! :3

Nope  that  is  not  normal  for  any  dad  to do  I  am sorry  but  he  is  not showing no respect   at  all  and  He  could  be  having  other thoughts  in  his  head , You need  to tell  someone  

My dad walks around naked all the time. My stepmom doesn't think it's weird because he's done this as long as I can remember. I'm 13 now, and a girl, but my dad doesn't care. I just try to ignore it, especially when he gets boners or takes a shower with me.

A lot of men do that, and at least he's wearing a towel and not nothing I guess it's because most men are quite open with themselves being naked around there house it's sort of like an "alpha thing"
