Wow, chill a lil bit, I'm personally amazed you have never clicked on the bot before now... having said that, about 2 versions or so ago, when your mouse hovered over the bot, it showed talk, and frick if you hovered lower down, as the game didn't have those little interaction squares, you clicked on things in the room (like the tv, cupboards, Pc monitor and the bot) to start interacting with them. The interaction squares were added to highlight room interactions, and I'm guessing that the dev assumed people had played a earlier version and already knew they could click on the bot.
but hey, you know now, so enjoy the game, try to find all the endings (but keep a save before hand, as all of them = game over, except 1 or 2)
