old woman

i was approaching a zebra crossing in my car and there was an old infirm woman crossing the road... she was being helped by a youngish man, it must have been her son, or grandson perhaps. she was shuffling so slowly it was extraordinary to see. and he was helping her with each step so very patiently and bending to smile and talk to her... stroking her back warmly... step by step... and i thought ''that is the definition of love''
