I wrote down the wrong date.

I took some cough medicine, it doesn't usually affect me, but sent me straight to sleep, and slept right though it.

My car broke down and I couldn't make it.

I had it all written down on my appointment book at work, but then got fired. They escorted me out of the building and won't send contents desk until after the investigation.

It's your fault, you were supposed to remind me.

I had to spent some time unexpectedly in jail, stag night/hen night that got just a bit out of control !

You mean party the was this year ?

Had one of those "stay at home or it's time for a divorce" discussions and just couldn't get out of it.

I had a relapse, enough said.
