Actual email I just sent to a customer:

"I logged into your account and I see the problem. I will update you and have it fixed either by tonight or tomorrow morning. It is a rare bug we have encountered before, and we are working on it as you read this. "

The truth:

"Im fucking drunk right now. I know that error. I put off fixing it for awhile now hoping it wouldn't come up because it's fucking annoying to fix. I'll try to fix it tomorrow morning, k no promises though. If I can't I'll still have your problem taken cats of it just means I'll have to do it manually. Anyway.. Gonna drink some more now, bye. "

P. S. There is no we. It's just me. K bye.
