Things that tick me off: People who can only read the first sentence of any email

Have you ever emailed someone to get some information about something, and they read only the first sentence of your email?

Example:

Message:

Hi, just wanted to confirm that you will be here at 11am Monday. Are you bringing a laptop or will you need one for your presentation?

Reply:

Yep, I'll see you Monday at 11!

Stupid stupid stupid
