Private things in my room

Yesterday I got home early and I heard my son downstairs so he wasn’t going to be a bother. I could hear his pitter patter light years away. So I decided to help myself in my room. I left my door open because I knew my mother in law was around and I hoped she could see me. She got near my door and I think she was trying to be loud to show she was near but I acted like I didn’t hear her. She left I came it was great.

so today. I got home and the mother in law said “if you are doing private things in your room?!”
for which I interrupted with “what things ?” I was being cheeky.
”private things”
”what? Was I getting changed?”
” Don’t make me say it, I’m 62 years old I don’t want to do that” so I played dumb.
“ okay no problem” to which her reply made me pretty happy
”and don’t mention it to your wife either “
“okay” so that was my afternoon. If she only knew I know what she looks like naked.
