Had a friend of a friend on Facebook. Similar interests. I didn't think any big deal. Then he started chatting. I don't usually chat. I said something about liking football, he offered to buy me some Jerseys. I said no. He then said some very explicit sexual advances. I defriended him and deleted my gmail account that had my name on it. Blocked him on FB. I started getting chest pains all day and into the next.
