blood curdling scream

the other day i was on my way to class, riding my bike, muffin. 
i was going around the corner by the classroom building (i usually don't even go that way, but the sidewalk i usually go on was taken up by a baby buggy ((hahaha sorry couldn't resist being british for a second)) aka. stroller). 
anyways.  i was going around the corner and suddenly i hear this blood curdling scream. 
i look up and there is this kid on a mountain bike - not even one of those little trick bikes (?) with the pegs so you can give someone a ride... bmx bikes maybe?  i have no idea. 
anyways.  this kid on a mountain bike is flying over the stairs.  i think on purpose. 
and then he totally landed his jump - i'm assuming he did it on purpose - and had this look of complete triumph on his face and just rode off into the distance.  but not the sunset.  because it was the middle of the day.  but it would have been a lot more dramatic if there did happen to be a sunset for him to ride off into...
the purpose of this story is the blood curdling scream.  i never knew boys could scream like that.  or ok: "men".  this was no small child.  i was pretty impressed.  just for the record:  i'm pretty sure it was more a scream of joy and less a scream of terror.  which is also a little strange.  normally (although what is normal, i guess...) normally boys, i mean men don't go around screaming just for fun. maybe boys do these days, who knows?  it wasn't considered "manly" for boys to scream when i was young...but that was a long time ago.  HAHAHAHAHAHAHAHAHAHAHA
interesting...
