You check the clock. You check again, because you didn't actually read the time because you were too absorbed in the process of checking the clock that you forgot to check the clock.

You check the clock again. You have a new email. You consider checking the clock again, but give up and accept your fate because checking the clock a (second? Third? Tenth? First?) time is just too much right now, you're already running late anyways so it was kind of all procrastinating in the first place. You don't even know what you were supposed to be checking it for. Just wait and see, it's probably not that important. Maybe you'll check the clock and see if it sparks your memory.

You check the clock. You finally see the time. The bus drives past you.
