Grampy surprises me all the time -- some are good and some are bad !!
Good ones, might be bringing me a treat, booking something or simply just saying on the spur of the moment lets go ….wherever.
Bad ones, he forgets he's 67 sometimes and does things that at his age he should know better. Like following the little boys 9,7 & 5 leaping into the paddling pool ( and landing with a tidal wave and skidding straight out the other side into the bush!! Or Coming into the garden and finding him up a ladder, precariously balanced with a hedge trimmer !!
Wouldn't change him for the world though .
