You take a look at the note, and discovered that the spray was actually from the coach of P.E that you remembered was very strict to all of you while you were doing exercises. You had no idea why he would send this kind of spray to you, so you decided to read the note to see what he had to say.
"Dear student," the note read. "I've noticed last year that you were having trouble last year with my class, so I bear an offering to you before class can begin. The sprays effect is permanent, but beware of the side effect it will give you once you spray it on your body, and be sure not to use more than one spray cloud of this stuff. From Coach Davis." You had no other choice, but to follow what the note has told you, while you take a look at the spray, and spray your armpit with that one spray cloud.
