Men in Trees

Or really just one man. In honor of spring, the maintenance crew has been doing a lot work around campus planting grass, clearing leaves, and trimming trees, as this man is doing.

I'm sure he's perfectly innocent and I know I'm being super paranoid, but this got me thinking. How do I know this guy even works for the school? How do I know he's not just some rando who likes to cut trees?! I'm pretty sure he does work for the college, but would anyone question me if I were up in tree cutting down branches?
