Telling someone to be more unique is a great way to build rapport
Story Number two comes from moi, but has a similar tone. Right off the bat I noticed kind of a pretentious tone - kind of talking about things in a braggy way but I figured it could have just been the way I was reading his messages so I kept chatting with him. The back story is that I mention my massive amount of first cousins and the fact that I'm thinking of investing in a claw grabber with various attachments such as lobster pincer, in my profile.

Then he goes on to tell me he has over 100 cousins and I say "first cousins?" and he says "no, 8 first cousins". So I say "fuck you and fuck your 8 cousins, I'm out." (but not actually...I just stopped answering and then he proceeded to view my profile about 10 times over the next few days. Probably while crying.)
