I can't be trusted. Trust me.

I contradict myself without even noticing it.

Ernest : "Joel, are you coming for training on Monday?"
Me : "Most probably."
Ernest : "I let you have the honour of keeping the store keys..."
Me : "Haha. I can't be trusted. Trust me."
Ari : "Trust you? I thought you said you can't be trusted!"
Me : " OH YA!!!!! hahahahaha"
