Allright, item one.

At some concerts I observe that the crowd parts down the middle, scrunching up on each other to make a wide divide.

Then at some particular part of the song the two sides run at each other. I don't get it.

Seems like it would hurt.

Great way for a concussion or broken limbs.

What gives? What is the fun?

Item two, engagement rings.

I'm not sure I understand this one.

I can understand wedding rings, but engagement rings just don't make sense.

So why do we have this custom?

All right, carry on.
