We had a kid in my 6th grade class named Rocky who was 15.
Dense as a block of lead. Way bigger than all of the rest of us. Quit school the day he turned 16.
Saw him at a convenience store about 25 years later and he was a little guy about 5'6" or so. Sweeping the parking lot for the Red Dot Owners for a six pack of beer. Still dense as that block of lead.
