You run into your kitchen and pick up the telephone - you had almost forgotten no one else was home to answer it. "Hello?" you say breathlessly.
"Hey, girl," your best friend returns. "Remember the party tonight?"
Your eyes get wide. "No, actually, I had completely forgotten," you reply. "I don't know if I can go, I had planned on going out to dinner with my family tonight... it's my dad's birthday, you know."
"Well, suit yourself, but I bet it'll be great. The whole basketball team is gonna be there - hot guys, man, hot guys! Come on!" she tries her best to presuade you.
"I don't know..." you whine. You really want to go to the party. But on the other hand, you don't want to dissapoint your dad. After all, there are parties and hot guys everywhere. Birthdays only come once a year! What do you do?
Go to the party - Dad'll understand
Go to Dad's birthday dinner
