What Star Wars Episode IV fails to reveal is that young Luke Skywalker once had a love interest on Tatooine.  Her name was Rose. 

Rose too had a knack for repairing droids.  Much like Luke, her parents kept her at home most of the time to help take care of the farm.  Their paths would cross though during a chance encouter in Mos Eisley one Saturday morning when Luke was sent in to town to pick up some parts.  Rose was a sharp shooter with a blaster rifle but it was this competitive nature that eventually drew them apart.  Rose was very playful at heart but at the same time didn't know her own strength.  Once she pinned Luke in a wrestling match so forcefully that it left him frankly intimidated by the younger but larger and stronger counterpart.  They would never meet again.  But I'd be willing to bet Luke still thinks about her from time to time...
