Harmon often reminds me to do things I forget:
Scratches me to let me know it's time to cut his nails.
Knocks over/kisses/hits with toys the framed pictures leaning against the wall to let me know that 2 1/2 months is long enough to not put them up.
Gets poop on his changing pad so I remember to wash it.
Finds cheerios and pieces of plastic on the floor to help me see it's time to vacuum.
He is a good helper.
