Question of ethics?

[FartinMowler]

I have customer that is this old dude 83 and I've been cutting his grass for around three years. So around a year ago he mentioned that he had a new "girl friend" (he is just joking) and as time went by he said that she is his bank manager and keeps inviting him over to her and the husbands house for dinners. I must spend atleast an hour everytime I go to work for this guy talking and he doesn't have any family left and in the back of my mind this couple that I met once is kinda creepy, should I report this to someone or keep my mouth shut?
