For me I don’t think it was a coincidence.
My story is: 2 years ago I was looking for an apartment. My friend who is an agent took me to an apartment. After viewing I messaged him on what’s app saying I liked the place but I want the landlord to put latches on the windows so it’s child safe.
After messaging him I went to Facebook. Scrolling the timeline. A minute later I have adverts for window latches and window grills for child safety.
I didn’t search Google or anything. I was shocked.
