My friend likes to learn new things sometimes, and he recently learne to juggle several items at once!
That's pretty amazing. I have tried juggling 3 small objects before and felt like it was impossible. 
Same here. I have no idea how he does it...but it's quite amazing to see. I'm somewhat envious
I can understand that. After my failed attempt, my oldest son, then 13, came in the room juggling successfully a few minutes later. He watched a youtube video and learned in about 15 minutes...
