dialogue: Karlene: Tina, are you coming to band practice this week? Our show is this Friday...only two days away!
  Tina: Yes, I'm coming tonight. I didn't come last week because my guitar was broken.
  Karlene: Did you fix your guitar? My sister has a new guitar you can probably borrow if your guitar is still broken.
  Tina: Thanks, but I can only play music on my guitar because it's a left-handed guitar...it's for people who use their left hands for most things. I fixed my guitar on Monday night.
  Karlene: Why didn't you fix it sooner? We only have two days until our show.
  Tina: I've been so busy this month! I have to work at the grocery store and watch my little sister until my mom comes home from work.
summary: Tina didn't come to band practice last week because her guitar was broken. Karlene blames her for not fixing the guitar sooner but Tina has been too busy this month.
