Ain't Too Proud to Beg, I need some help.

This weekend I am stepping way outside my comfort zone and going to the Rolling Stones concert at The Shoe.

Here's the kicker... it was my idea.

Something about showing C I'll try new things.

Here's where you all come in because I've got a few questions:

1. What do I wear? Do I wear something torn and frayed? I have a feeling my current wardrobe (which isn't large to begin with) doesn't contain the right outfit. 

2. What if it rains? WHAT IF IT RAINS? The concert is outdoors.  I feel like I should've thought about this before purchasing the tickets. Who's going to gimme shelter?

3. What time will the concert be over? When I purchased the tickets I thought "Oh, great. It won't take long. It starts at 8:00 p.m. so we'll be home by 10:00 p.m." Then my mom said the Rolling Stones probably wouldn't get on until 10:00 p.m. 

4. Who are the Rolling Stones? I can almost hear you sigh.
