Morning Routine

Here is the start of Pete's morning routine. It varies, depending on whether Sam takes a shower:

• "A" day: This is the day that Sam takes a shower before Pete. Pete gets mad at Sam for not getting out of the shower until 7:50am, and then gets in the shower at 7:51am.
• "B" day: This is the day that Sam does not take a shower. Pete gets in the shower at 7:51am.
