Your best friend was Skyping him when you walked in and he insisted on meeting and talking to you.

He spots you at a concert and refuses to leave stage until you agree to wait for him.
Niall:
Your friend won a contest that allowed her to talk to Niall, you happen to be at her house and you talked to him with her.
Liam:He puts on a U-Stream and your comment makes him laugh. So he later finds you on Twitter and direct messages you.
Zayn:You unintentionally run into him at your favorite restaurant and he smiles right when he sees you, and asks you to join him.
