We often write short messages to family members，friends or classmates to remind them about something．Short messages are often written clearly in a few words．Here is an example．

18 Sept. Hi Jimmy，     This is to remind you about our basketball game tomorrow evening.     I'll meet you outside the club at 8 p.m. Don't forget to wear your basketball shoes.     See you there!                                                                 Simon
