My kids told me about this last year. Here is something to try…. Put your phone on the table next to you and mention the same topic at least 10 times in conversation. Something like “We need to go to Hawaii” or “I want to buy a new house” or “it’s time to have another baby”. Etc. make sure you say it at least 10 times or more as part of a conversation then watch what ads you are shown are about over the next few days on every platform with ads. It’s not just facebook. It’s scary as hell once you notice this. There are no secrets even in your own home! Big brother is here!
