The Dink Network

I'm trying something like that but if the player can press enter he can change weapons and spells. But I'm asking this because I want Dink to be able to sit on a chair. I have graphics for that (Thanks Rabidwolf9!) but now I want something like you touch or talk to the chair and that you sit down then, or should I say the fake Dink but then I need him to get up without the real Dink doing stuff and without him being able to do nothing else he can't get up because there's nothing were the script will react on. So the best thing would be Dink talks to the chair, a choice appears sit down or leave; Dink sits on the chair able to talk (because he's in front of a bar and else the chair would be useless anyway and also able to bring up a choice menu that says get up and leave. So.. any help?
