I am looking for some advice about what to do now please, as something doesn't make any sense. About a month ago I found a pair of knickers that weren't my size. I had managed to wash and dry them without noticing, it was only when I went to put them in the drawer that I noticed they weren't mine. Not my size. At the time I assumed that they had been my son's girlfriend's and that they had been somehow mixed up with his stuff. My son and his girlfriend had recently returned from a holiday so it seemed likely that is what had happened. I mentioned to DH that I had found a pair of knickers which I assume were her's.
I was waiting to see my son's girlfriend to ask her if they were her's. In the meantime, I had put them in my underwear drawer. She hasn't been round since then although I have seen her away from the house but I forgot to ask her if she had lost some underwear.
This weekend, I went away without DH. Putting away the washing today I notice that those knickers are nowhere to be seen in my underwear drawer.
There is categorically zero chance of my son going into my underwear drawer. I hadn't even told him about the knickers. The only other person who could have taken them is DH but then wouldn't that be a stupid thing to do as I had told him that I had seen them? What do I do now?
