The time i almost got robbed on a museum

One time my mum told me to go to classes on summer break at a museum. It turns out it wasn't classes just like a random art dree time which I didn't even talk about, I just said good afternoon then it just lasted like 15 minutes and the poster said 2 hours so an old lady came and stayed with me a bit and left, I entered to the museum again when I saw like 3 guys checking me out when my mum came I ran out of the museum crying (I was such a cry baby wth)
