Being on a PvP server in The Old Republic.
1: Logging off because a group of level 50 Republic characters are camping a spawn point.
2: Holy shit, I didn't even know anyone else was in this place. Huh, guy's same level as me. He's not attacking. Guess he's wondering what my deal is? I'll just walk past him, see what... yeah, okay, he knows I'm ignoring him now. Guess we'll just car- no, wait, our companions started fighting.

it, I'll just kill him.
3: Holy shit, I didn't even know anyone else was in this place. Huh, guy's same level as me. He's not attacking. Guess he's wondering what my deal is? I'll just walk past him, see what... okay, he's following me. Shit, not following: stalking. This is actual, real-life predatory animal behaviour. Like, this is a thing that bears do when they're hungry and want to eat you.

it, I'll just kill him.
4: Haha, that guy has, like, 10 HP left from a hard-won fight against an NPC.

it, I'll just flying tackle him.
