Sam tried to hide it.
It wasn't hard to disguise it from the object of his affections, but he saw the looks the others gave him. The pitying, angry and/or disgusted looks.
It was wrong, so wrong, but Sam couldn't stop himself. He was head over heels in love with a giant, alien robot!
But of course, said giant, alien robot was oblivious and didn't even consider the possibility.
So Sam kept quiet, hid his "sick, perverted" obsession away, and lived his short, human life.
The one he loved was the only one surprised when he lived, and died, alone.
Ok, so there are quite a few one-sided Sam/Autobot or Decepticon relationships out there with Sam as the oblivious one, therefore I decided to write this 100 word drabble with it the other way round. The "giant, alien robot" can be replaced with any mech or femme you like.
