Ça m'embête...

Annoying:

When you email someone about something they asked you to email you about (like say, to schedule a meeting), and in reply to said email, you get something along the lines of "Call me and we'll set something up." But when you call, this person doesn't answer. Or call back. Annoying.

Seriously, email works too. At least with email I can delight you with my prose instead of having to leave an embarrassing voice mail message. It's like a trained ballet dancer being forced krunk; it might be fun to watch, but only because you know it's going be a train wreck.
