How does cold approaching even work?
It doesn't kek
Apparently, you don't have to talk about objective things and real informative things (that's a reflexe males usually have : we don't initiate conversation unless we really feel like having something to say). Foids constantly use conversations to entertain themselves or to kill time : that's precisely the kind of conversation they find charming, interesting, worth their time, whatever.
The problem is most mass approaching incels (and male in general) are very "functionnal" in their way to talk and communicate. We often have a hard time trying to please girls because we don't use the same grid as them to evaluate unconsciously the quality of a conversation.
To make it simple : try to talk about feelings, stuffs with no logical links, social interactions, etc. Also the weather, things you see right in the street, people around you, boring stuffs.
I don't mass approach because I find it plain boring and intellectually disappointing. The day I will not be able to cope anymore, I might pay some cheap prostitute so that she do me the job and voilà.
