You know the ones to which I'm referring.
The always-together, chemistry more prevalent than in the science building, sparks flying as if you're at a small town summertime barbecue 'friends'. The "you're a dork, but if anyone else says that, I'll punch them in the face and then flick them with my ponytail as I walk away" 'friends'. The "she was cute; maybe you should go for her (but that's an absolute lie)" 'friends'.
I've been there. I get it. You love him. You love him in a drive 3.6 miles to the nearest 24 hr Walgreens at 2 AM for Fruity Pebbles type of way. You love him in a pretend to hate driving in favor of being his permanent shotgun rider type of way. In a watch him write numbers in binary code or play hours on end of Super Smash Bros type of way.
So do it.
Love him.
Love him in all those ways and more. But most importantly- love him in a be his 'just friend', when you resign you cannot be his 'I love you', type of way.
Support him in every possible aspect of his life. Laugh at his terrible jokes. Be his go-to for anything and everything. Be his first "hey!" and his favorite "see you tomorrow". Make friends with his roommates and be kind to his conquests.
Give him no reason not to love you in return; we all know he does-and will- anyway, he just needs some time to grow and realize that you are indeed what he does not know he is missing.
Be completely and brutally honest with him.
Tell him up front when he is not being your favorite person, and tell him twice when he is. Buy him two Three Musketeers bars when you're buying yourself a MilkyWay, and tell him that you still love him- even though your candy choice is superior because it includes caramel.
Offer to help him clean and then let his 6'7" self-hold the dustpan as you sweep because "the floor is too far away" for your 5'4" figure to squat down and do it instead. Memorize his Subway order subconsciously- and more quickly than any of the workers- even though it's useless, as you know that if either of you goes to Subway, you'll be joined by the other.
Travel to his hometown and meet his parents on a whim- wearing a t-shirt and your trusty Nike sweatpants. Make them love you anyway somehow and let them tell him on their own that they like you and think you're "the one."
Laugh when he tells you this- trust me. It will take him a while to realize that they know best.
