BOTL let me down

Yesterday I wore a frown
Because my BOTL let me down
We were to meet for a smoke at 2
but it was 3 before he'd shoe
I was very sad and cried a tear
and all day I wore a frown
Because my BOTL was not around
Yesterday my BOTL let me down...


Not meeting on time for a smoke at the local tobacconist is one way a BOTL can let you down. What are some others?
