Dear Mom,

How are you? I hope you and Dad are doing great. My friends are planning a trip to Canada. They're going to Niagara Falls, Montreal, Toronto, and many other places. They're asking me to come along, but the date of the trip clashes with Jessica's birthday. Mom, I had promised Jessica that I would come home for her birthday. But I also want to see Canada with my friends. What should I do? I can't make up my mind.

Love,
Naomi
