Acceptable excuses

- Death
- Serious Accident
- They are Superman and there was a crisis with a bus full of school children in Africa

Weak excuses

- I'm really sorry I just lost track of time
- I was working late and couldn't get out of it
- My phone died and I couldn't let you know I was running late

Unacceptable Excuses

- My wife that I didn't tell you about has just gone into labour.
- I've realised that I don't really like you and decided to ignore you completely and hope you go away.
- I was on my way but a bear came out of nowhere and bit my hand off... whilst I was holding my phone! Why do I still have two hands? Err... it got better...
