I've began to think that my father in law exposes himself on purpose

My father in law is a great guy and very kind to me and my husband, but I'm starting to think he intentionally walks around naked in the house knowing I'm there.<br><br>When my husband and I visit his parents for more than a day we usually sleep in my in laws room and my fil will sleep on the couch with my mil. They don't have an extra room so this is our only option. <br><br>So the first time this happened was when I got out of bed in the middle of the night to get a drink. It was pitch black and I turned on the lights and fil was standing there with literally no clothes on and just clearly saw his "junk". He apologised to me and went to the couch.<br><br>Then it happened again when I had to come downstairs to let the dog out. Same thing. No clothes. He apologised and went back upstairs.<br><br>The last time was very weird. He was in the kitchen making himself a snack. I came down to talk to my husband and fil had no shirt on. I thought whatever, I don't care, until he turned around and he had no underwear on and his shorts were see through. He "didn't notice" that I was there until I very loudly and awkwardly coughed. He "apologised" and went back upstairs. After that happened my husband and I immediately left.
