happiness

I visited my childhood city yesterday.....i felt it like i used to feel home..years ago.i felt my feet digging into the earth like it was mine, i felt small, being carried, being taken by the scruff of my collar and patted and brushed....i actually felt my parents, and their memory seemed so much more real...it takes so little to feel happiness, a terrain, memories, a voice maybe? why do we deny ourselves and others of this?
