Never swipe at a flying insect that's in your face that you think is a fly, it may turn out to be a wasp and come sting you right under your eye, I had to learn the hard way and it hurt really bad

this ended up happening in the school gym while me and the rest of the JV volleyball team were helping the varsity team warm up for their scrimage time since we had just finished ours. Then my eye started swelling, I had to ice it during the whole time varsity played.
