E: NVM I see you're implying my helmet's cracked..My friend has my helmet still I'm finding out whether its broken right now
Your helmet needs replaced. Don't ride again without replacing it if you hit your head that hard with a helmet on. It's just like a motorcycle helmet, it's designed for one hit.
Go to the checkup though, any info the doc can give you will be beneficial.
About the parent thing. If I were to land on someone sitting in the landing without that person already being injured, I'd stop, wait with them for ski patrol but wouldn't even consider apologizing. Letting your kid hang out in a big jump line is like letting your kid play on a snow covered highway when a driver can't see over a hill in the road. The problem is that half the time I see someone sitting in the landing or riding between large jumps, usually the parent is right there with them.
