You clearly go to a good school, with high standards, which probably costs a fucking fortune every term (I'm not judging, I went to the Royal Grammar School in Newcastle, wore suits and generally got detentions for being late as well).
The upside is that you will have teachers who will actually notice and make note of things like lateness, because they generally want their students to excel and go on to great things. Not many successful people turn up late.
Now, in your situation there was some unavoidable instance - getting a puncture - that compounded your situation - running late already.
You withheld the whole truth and this backfired on you. So what have you learned?
Do you think you'd be in detention this saturday if you said "I was running late this morning when I left the house, and then unfortunately I got a puncture, hence me being 20 minutes late" in the beginning?
All of a sudden, that puncture becomes the primary reason for you being late - anyone, even your head of year, knows that a puncture takes at least 15 minutes to fix up. Now 20 minutes doesn't sound so bad.
In short, you have just learned the power of honesty SamJT. Use it well.
my two cents
