<human>: I was just at a department store, buying jeans and in the dressing room, someone had left a pair of  nice sunglasses in there.

They weren't from the store, I know that. No tags and you could tell they had been worn. Someone had just forget them while trying clothes on.

I thought, "hey, free sunglasses" and took them.

So was walking around with them in my shirt pocket and was making my way around the store some more with a few things in my hand to buy (I don't steal stuff) and I overhear this guy asking his wife (kinda whiny like) to go into the dressing room and see if he left his sunglasses in there and I'm just walking by when he turns to me and goes:

"Those are my sunglasses!" and he proceeds to take them out of my shirt pocket and I ask, "Are you sure?" (Knowingly quite well they are not mine.)

So I jet for the register across the store from him, pay for my stuff and leave.

Awkward for me, but I really hope he has a good story to tell.

Summarize the given text in a few sentences.
<bot>: Found some guy's sunglasses in a dressing room, took them, but then he saw them in my pocket in the store. No more sunglasses.
