Dear Roommate
(or more preferably, flatmate because even if we aren't in England, we don't share a room. We share an apartment):Thank you for making me breakfast yesterday when I woke up late because I failed to set my alarm to wake me up.
I know that my waking up late delayed your getting in the shower, so I appreciate you making an effort to help me get out the door (and even be to work early).
Hopefully this won't happen again (fingers are crossed....)
With deepest appreciation,
Emery
