kaely - Waiting until the last second to do something, and then it's

Waiting until the last second to do something, and then it's too late. You messed up big time.

I waited too long to finish my homework. Now I'm stuck with a 50 on the test.

I waited until the end of the week to ask her out. She already had a boyfriend.

I waited too long to tell him I was sick. Now he's got the flu.
