One bad night

I woke up with a strange voice in my head,
With a massage someone has ever said.
Don’t be dumb, don’t be shy, and if you aren’t, don’t go too far!
The first and the last I just did,
That night I drank too much, and that was a proper hit.
I did things I shouldn’t do, I don’t know exactly what happened…
All I know is that it wasn’t too good.
All it can say by now is,
Sorry for being dumb, stupid and ruining it all,
But I learned my lesson, and never forget I shall!
