A hug can be worth a thousand words. We moved a gent from his home (different means of transport than my own amb) not long ago. His wife, whilst trying to be helpful also kept interfering, getting in the way, telling us to be careful, generally over-fussing yet pragmatic that hubby would not be long for this world. At one point i had to be firm and tell her to calm down/back off ( i forget my true words) but i did so with a wee hint of humour so that the admonishment would be taken well. We saw her husband off in the other vehicle and i returned to the house along with her special needs son making sure he was ok with things. I confirmed where hubby was going. She apologised for the way she'd been and promptly gave me a big hug and this was followed by her son doing the same. More than words! It goes both ways
