I was 6 or 7 and in a pet shop with my mother and brother. There was a monkey at the back of the shop in a cage (I know), and my brother and I were up looking at it. My mother thought we were too close or something so she came up to move us back. As she bent down to speak to us the monkey grabbed a handful of her hair and would not let go. It pulled her head against the bars and my mother started screaming. The man in the shop ended up having to cut her hair to get her free. He was very apologetic. My brother and I were left traumatised. My mother was left traumatised but also with a bald patch.
