Try this as a test. Just choose an utterly random thing that has as little connection to anything in your life as possible. Then just start talking about that thing for a few minutes near your phone. Then never talk about it again.

Then tell me if you start to get ads for it. I think you will. I've seen it a few times.

One recent time, I was sitting with my wife and we were joking around and I was like "Why don't they have hamster wheels for cats?". We spoke about it for a minute or two and had a laugh. She swears she didn't google it and neither did I.

The next day we both got ads for this (apparently they exist).

I concede that it may have been a one off and there may be explanations.
