Keir is an amazing person. He deserves the world and all the happiness in it because that is what he gives out. He's like an exothermic reaction of a human, if he even is-don't get me started on how unhumanly gorgeous he is.
Me : Keir did *insert sweet/kind/generous/good thing* this morning.

Brother : that's so sweet/kind/generous of him, I'm so happy you're with someone so good for you.

Me : I knowwww I love him so much
Brother : I can tell

A Keir, is a person unlike any you have met.

You’ll often go throughout life and rarely meet anyone quite like him. Some are a close call and others will remind you of him, but few are like Keir. A Keir is obviously a rare breed, but when encountered they always have an impact. He’s a sexy spontaneous guy that can always make you laugh, with a kind heart and a side so wild that even those well traveled have a hard time keeping up. He crazy but like in a good way, and enduringly sweet and loving.

He can make you laugh hysterically or move you to tears through his words. He has Introspective thoughts that he kindly shares, and always tries his best and means well to all.

You’ll think about things he said when you try to sleep at night, when you see him, you’ll be glad he’s there. He affects the mood of a room by simply being a part of it.

There are those that don’t understand, and hate on Keirs out of ignorance or being to simply to comprehend what a special being they truly are. Even as I write this I may never fully understand what he is. but the haters will be in the few, as for many, if not all will say Keir , I love you.
Person 1: You’ll never meet another Keir
Person 2: Lol no shit.
