Go fly a kite

One sunny summer morning a father is in the back yard trying to teach his young son how to fly a kite. He isn't having much luck, no matter what they do the kite will only go up a little bit before it does a nose dive into the ground. Mom is watching from the kitchen window and decides to offer some advice as she was quite the accomplished kite flyer as a young girl. She steps outside the back door and yells out that to dad that he needs more tail, Dad calls back to say, "make up your mind woman, last night you told me to go fly a kite.
