1. At gym.
  2. Take padlock out of trousers.
  3. Unlock padlock with keys.
  4. Place keys in trousers.
  5. Place trousers in gym locker.
  6. Place rest of gear into gym locker.
  7. Close latch.
  8. Padlock latch.
What could possibly go wrong? I’ve locked the keys in the gym locker. 
  1. Then thought I’ll do session & get staff to cut lock at end.
  2. Chose to go back & try lock don’t know why.
  3. Door opened as it wasn’t latched.

Don’t make either mistake separately let alone together !!

I think some one is trying to tell me something !!
