On making promises

"How did you come to like stars?

-When I was young, my dad sent me a telescope for my birthday. He wrote on the card, "Study the stars well, so we can go watch them together next time."

So you went to watch the stars with your dad?

-No.

Huh?

-We never went, not even once.

Why not?

-Believing in that promise, I studied so hard I could have become an astronomer. Do you know what I got for Christmas a few years later? Another telescope.
That's when I realized, he didn't send the first gift or the card, but that his secretary did.
Do you know what my dream is?

To go watch the stars with your son?

-No. To not make promises I won't keep."
