How to get someone to carry something for you
When you hand someone an object while they are speaking and you are in the middle of a discussion, they will grab it from you without knowing it. It’s also true that if you extend your hand, they will give you whatever they’re holding.
They will be absolutely taken aback by what they have just done and will be stunned for a short second after they receive or offer the object. Undoubtedly, it is an effective way to make the other person laugh.
