The only ones who get a kick out of my computer knowledge are my mom and dad, and that ain't sexy.
You violated one of the cardinal rules of techno-sexuality: Never give your parents a computer unless you're prepared to become their perpetual help desk -- 'til death do you part. Just buy yourself a "cool messenger bag" and hope someone someone doesn't beat you up because they think you're gay.
Still it's amazing how good a job you'll do when it's for a pretty woman who's batting her eyes at you.
