Well, firstly, you can't start taking advice from other people, it needs to flow naturally but you just need to stroke his ego and every guy likes to consider himself funny, so all you have to do is other play how funny he is over the internet, plus a guy loves a girl with a sense of humour.
Everything and anything Omg I used to talk to this guy I liked everyday about everything music life love wants fears hobbies school drama friends anything but I lost connection with him and we don't talk anymore anyway just know there is soo much in the world to talk about.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
