Well said @devann.

It's scary and crazy these days how our personal space are invaded at will.
I once chatted (physically) with a friend about my intention of buying a new shirt and the next thing I know, all sort of ads for a new shirt from big online stores kept pop-in on my phone's web browser few hours after I had that discussion. I was shocked and remain so even till this day!

Be smart & vigilant out there... If you know, you know!
