Dad was right. I just wanted it because of reasons. - eh?
He disappeared for a time and returned with something that almost disappeared in the palm of his hand. It was the planet!
Repetition of disappeared.
I really rather like this. It's quite touching and very unlike your usual writing. It's always good to stretch (although most of us don't try to stretch across a galaxy).
the first line you mentioned -- it's just slang. i see it at tumblr a lot.. where the "reasons" are either unnamed, unable to put into words, or based on selfishness.
thanks for the second set of eyes. glad you liked it.
