Armani touches things. A lot of things. Like a little kid playing I Spy against their sibling, but instead of obnoxiously shouting out the names of every object in sight he's flailing his little arms around to touch anything within his reach.

MEMORY: Saying Goodbye
Door. Window. Wall. Ceiling. Sister. Mom. Brother. Other sister. Table. Counter. Cabinet.
