What's up, big brother? Doing okay?
We should totally try 2 catch a ride to the mall next week. Mom's birthday is
coming soon, so we should get her something cool. Just buying flowers and
candy again would be SO boring, LOL. Let me know when you'll be free.
Luv ya,
Sis
Rewrite the email so that it uses formal English.
Dear older brother,
I hope this message finds you well. I would like to propose that we arrange transportation to the shopping mall together next week. Our mother's birthday is approaching, and it would be wonderful if we could purchase a unique and thoughtful gift for her. Simply resorting to the cliché options of flowers and candy would be rather mundane, don't you agree? Please inform me of your availability at your earliest convenience.
With affection,
Your sister
