Write an email to my friend Shara. Let her know that I will be running about 15 minutes late for our lunch tomorrow, but assure her I will be there. Make it a casual tone and start the email by asking her about her day. Sign it with Love Janice.

Hey Shara, 
How are you today? I wanted to let you know that I'll be running late for our lunch tomorrow. I assure you I will be there, but roughly 15 minutes behind schedule. I look forward to seeing you there. 
Love Janice
