Charlie looks too small here. But you can see he was a good friend. =)
He may be on the smallish side, but he certainly seems determined to pull that mower. Some guy I dated rented a house where he was provided with only a rusty old push mower, although there was only a small strip of grass to tend to between the front porch and sidewalk and between the back of the house and the garage it was still a pain to mow them.
It looks like Charlie's wearing a cinch belt in this photo. XD
