I was in the supermarket quite early this morning, so it wasn't very busy.
In one aisle I could feel a fart coming on and it just so happened I was passing the only other person in that part of the aisle.
I don't know whether anyone else gets this, (I don't very often) but thinking about doing it really made me laugh inside and I had to fight hard to keep the laugh from escaping, and I silently dropped one while I passed them 
Now I feel really, really bad that I was so infantile to amuse myself by potentially causing discomfort or embarrassment to another person while they were innocently chosing which fabric softener they should buy.
I can never make it up to the person, so how can I redeem myself and shake off the guilt?
