Friends

They know most or all the quirky stuff about you.
They listen or comfort you in silence.
They go on random adventures with you.
They make your day brighter with their own quirks.
They take the time to be with you.
They cook for you...sometimes. :)
They volunteer (sort of) to be a guinea pig for cooking experiments.
They know when to give you advices.
They know when you need to hear the truth, whether it's harsh or not.

But most of all, they love you for being you.
