Thanks everyone.
I was at the local mall, at the supermarket actually, and the pochette was inside my bag, a plain, canvas bag (not an LV) that doesn't close on top (kinda like a Neverfull meets Galliera type of bag). It was hanging of the handle of my son's pram (a Stokke, so it was kind of high, but not really firmly attached to the handle). I was taking my time doing the shopping, like, I'd stop at one shelf, maybe walk a few feet further with the pram to my right or left (I'm always looking at the pram/talking to my son, but I'm not exactly keeping an eye on the bag itself, cause it's completely hidden by the seat of the pram, yeah... stupid of me) A couple of times I had to reach all the way up or down, to get what I wanted, and eventually I looked at the bag, and saw that one of the handles was hanging all weird... I immediately thought of my little LV, and sure enough, when I looked into the bag - no pochette in sight. The staff at the store looked at the surveillance videos, but they said they saw no one suspicious. I was just kind of in shock, and very upset, cause obviously not only had I been robbed, I couldn't even pay for the food I had to buy, my licence was gone, I just wanted to leave that place asap, get home, and start cancelling all the cards, making the calls etc.
Lesson learned I guess. I appreciate all your kind words. Thank you!
