I've just been into a large charity shop, with many racks of clothing in it.
I was the only customer in there and was looking at one rail of clothes when a man came in and stood right next to me, looking at the same rail (of women's clothing) with his arm touching me.
I moved across the shop and he appeared next to me again soon after and again stood right next to me 'browsing'.
So I moved another time, and again he appeared next to me, arm touching my arm again.
I then moved quickly to get away from him and tripped but didn't fall and he laughed loudly.
Why do men do stuff like this?! Why can't I just browse for 2 minutes in a shop without a man invading my space?
