The mistake a lot of guys make is treating IOIs like some kind of checklist or “permission system.” Like they’re waiting for 3 clear signals before they do anything. Real interactions don’t work that clean.
In night game especially, everything is more chaotic - loud venue, alcohol, groups - so IOIs are often subtle or inconsistent. A girl might be interested but distracted, or just vibing in the moment without giving obvious signals. If you rely too heavily on IOIs there, you’ll hesitate and miss opportunities.
