Overbooked

I decided this semester that I would only go out twice a week (plus the temple on Fridays, which makes thrice) because school needs to come first and stuff like that. So how did I end up with tickets to three different shows this week? Because I am completely incapable of saying no when offered free tickets. Here's what should have happened:

"Catherine, would you like tickets to a show this week?"
"That's really nice of you to offer, but I still have a lot of reading to do on search engines and a website to create, so I'll have to pass this time. Thanks anyway!"

Here's what happened:

"Catherine, would you like tickets to a show this week?"
"Always. Just tell me when and where."

Will I ever learn? Not likely.
