Go to pool party, get in pool. Find out pool actually closes at dusk. Proceed to swim and drink anyway. Cop shows up. "Pools closed, you gotta go". We leave. No drama.

That was a seriously cool cop. Didn't ask about the drinks (no glass, but still). Didn't card anybody. Didn't even go into super dick mode. That was a SERIOUSLY cool cop. Everyone at the party was also seriously cool about it. Nobody gave him crap about it. Nobody got defiant. We all just left peacefully. Why can't it be that way all the time?
