A short scenario, you became so bored to learn over something, very hard to teach something you don't want to learn, a sharp guy calls you to short cut to you what you want, explains to you clearly because he knew you don't want to learn, you became lossed and be a victim of been scammed.
What if you have learnt, you can't be smart all the times, you must surely make mistake which everyone does due to one lazy moment to another, you find out you already in the trap.
Lesson: Never do what you don't understand, learn something first and be careful at all time even when you have learnt it. Doing that will spot out scam gradually.
OP, you emphasize very strongly that beautiful girls can invite you.
Haha, this is funny
