My stomach growls in exams quite often and I hate it because its so awkward.
And once the bell rang and I was alone in the house, so I went to check who is it, I looked through the hole and saw a woman, so I thought she was my mom, so I opened and then I realised she isn't, I didn't know what I was doing and then I closed the door while the woman was talking.(looks like she was a businesswoman or that she was begging)
