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
