how you pass your time when some one bore you

Oh, this is an interesting question! I am getting worse and worse at hiding my boredom as I age. My kids tell me I sigh very loudly or take extra deep breaths that are very noticable when someone has bored me nearly to tears and I am dying for escape. Now that they have made me aware of this, I will try to exit the conversation or room earlier, with some excuse, most likely, instead of hanging in there and huffing and puffing my frustration!
