When you decide to donate blood to avoid studying.
I had a 2 1/2 hour break today and was going to use it to study, but the blood donation truck was at my school and I was like WHOA FREE COOKIES. Let's do this.
Also I actually am a relatively regular blood donor and they often ask me...incessantly...to donate blood as I'm O+, so I figured I should now before I start any medications. Not sure how that would work with donating :/
Plus I got free Oreos and apple juice.
