Replying to Landed on some guy

yep today i hit like a 30 foot step up with a 180 and hit some guy. I took off thinking noone was dumb enough to stand on the other side of a jump landing but this guy was. When i do 180's i dont look over my shoulder to spot my landings so i was about to touch down and i hit something really solid. I looked over my shoulder and saw some guy fly like 20 feet and then tumble pretty good. Yea he was ok so I just kept goin in case he was mad. The cool thing is i like bounced off of him and kept spinning and completed a 360 and rode away. My back is sore tho.
