Sure but did you have any other interaction with the internet about these topics? Did you search Google for tree house building codes? Did you search Pinterest or Instagram for ideas?

I have heard this anecdote many times but I don't believe Facebook is actually recording everything we say. Mostly because I don't think our phones have that kind of battery life. I do think they have data on essentially everything you do online.

I wonder if it is also possible they associate you with searches your friends have done after being in the same location? So if you chat about going to Bali with your friends or co-workers, and one of them searches for Bali flights, they then display Bali ads to the entire group.

This is true, they are known to monitor location all the time and display ads like this. They will also suggest people to be friends if they find you guys hang out in person a lot.

Another common one is credit card data. If you buy a special razor at Kroger, expect to see ads about mangroomer on FB.

No. NO interaction with the Internet.
