Should I tell the neighbour what their kid has told me?

I was just sitting here on the couch scrolling through Reddit on my phone when the neighbours from a few houses down 6 year old boy came over to play with my son, He saw me on my phone and asked me "Is that Tinder?", I said no then asked him how he knew what Tinder is, "My mum uses it a lot to look for new boyfriends even though shes married to my dad" he said. I didnt know how to respond to that one and just said thats interesting and left.I dont know if I should bring it up next time I see her, it would probably be a bit awkward. via /r/Parenting https://ift.tt/2OfsWky
