L1/R1 scrolls through your inventory, and your active inventory item is assigned to. The left stick controls Larry, while the right stick controls the on-screen cursor. If this happens to you, you'll definitely want a save to load up! Make sure you're making manual saves while playing! This is especially important, because sometimes your controls can lock up and you can't progress with dialogue.
You'll often have to exhaust it, anyways. Unless otherwise stated, dialogue choices don't matter.
