Did any of you have parents that walked around the house totally naked? Do you think that's normal?

My dad used to always walk around the house naked and I didn't really think much about it at the time but it seems a little strange. However, thinking about it, my mom didn't.

Also, one time I was at a friends house after sleeping over and we were watching cartoons when his mom walked right across our line of view and into the kitchen completely naked. She saw me sitting there and acted surprised but kept going. I obviusoly didn't mind at the time but for my friend it semmed a little strange.

Later I found out that friend of mine became gay. Do you think that had something to do with it? I could just see that maybe every time my friend was with a woman he thought of his naked mom and it screwed him up...

Or maybe it totally fine. Any thoughts?..
