"Go into a centre and interact"

"Go into a centre and interact", but what if you don't know how to/you struggle to grasp the rules of social engagement. There's a presumption it's all just about stepping through the door, and hey presto a social network will soon develop.
Reality for some of us: Step through the door. Find chair to sit on. Struggle to approach anyone and initiate a conversation. Spend the time gazing round the room. If someone does approach you you then struggle to make small talk and sustain a conversation.
