Of a time you were forgotten or left in an embarrassing situation. Either by friends/family/SO. I'll start.
When I was 13, I went to have my wisdom teeth removed. My mom took me to the dentist, and then left. Unfortunately, she was gone a lot longer than it took for my removal, and I ended up spending almost an hour sitting in the waiting room for her to come back. The whole time, I was stuck in the waiting room, drooling blood, mouth packed full of gauze, and half knocked out. I was sooo angry that she left me there.
Now you.
