You are in your ‘comfort’ zone. You are safe in your room, sipping your tea, maybe in a robe, as relaxed as you will ever be.
You sit at a computer, communicating with your friend, (who you have never met) on the Internet.
You are the perfect target.
The Scammer, your friend, who you think is (whatever they want you to think; from an old school mate to a professional) posts something.
Maybe it’s a veiled request for money or whatever it is that they want.
You are perfectly willing to give it to them.
