I miss you greatly.
I miss your greeting when I come back.
I miss seeing the shape of you.
I miss your presence.
I miss sitting beside you, enjoying your silent company.
I miss watching you eat, watching you drink, watching you sit there in great patience looking at what's around you.
I miss your touch.
I miss the softness of you.
I miss trying to figure out what you need and what you want.
I miss you jumping onto my bed and trying to squeeze in beside me.
I miss carrying you out of my room when you try to scratch my bags.
I miss stroking your head and just sitting in the living room contemplating about things that happen.

Heh.
