So my teacher gave me back my quiz today and I got one wrong. It was only 5 questions so I got a B instead of an A. But I know I got it right. It says "Johnny and Logan are at a party. Mary had a little too much to drink. Mary, Johnny and Logan go upstairs to a room. If Mary has 2 balls in her mouth, and 1 ball in her butt, how many balls are hanging free in the air?" so I said 1 and I got it wrong. I asked my teacher and she keeps saying she'll show me tomorrow after school. Now I'm nervous and can't sleep. What should I do?
