I have had something similar, but with a sickening twist.
June/July 2021.
I was in the kitchen, batch cooking prior to my return to work from maternity leave.
I had the kitchen door open to the hall, so I could hear if DS awoke from his nap. I could see the front door, and porch door.
I had the backdoor (from the kitchen to the back garden) open, as it was hot. The side gate, from the front garden to the back garden was closed.
I saw something in the corner of my eye, span round to see the postman inside my kitchen, putting a parcel down on the floor.
I screamed in shock, said something like "you made me jump" he smirked and walked off.
He had not tried the front door, because I would have seen him through the glass, and he could have left the parcel in the porch.
Instead, he walked around the side of my home, opened the side gate and then walked in through the backdoor and into the kitchen.
I did not complain, because he had just started to wear a skirt, full face of makeup and a long brown wig, and I was terrified of being accused of being transphobic.
I'd seen him over the last couple of months dressed in the male uniform, with stubble/male voice). This was the second time I'd seen him dressed that way. If I had been accused of transphobia, I'd have lost my job.
However, I wish I had complained.
He did similar to a neighbour, who found him in her back garden.
I saw him a few more times, still dressed in a long wig/excessive makeup, but driving the post vans, rather than walking the rounds. I did wonder if someone else had complained.
Caveat - dress/present how you like. However head been dressed, he still crosses the boundary that day (in more ways than one).
