I do and DH doesn't and it sometimes causes friction. So if there's something that I'm supposed to be doing I'll narrate my thoughts out loud like "I'll just do xyz then I'll get on to abc" or if we're going out I'll say "I'll just go to the loo/get shoes on/whatever then let's go" whereas DH does not do this. He'll just disappear leaving me standing at the door wondering where he is, how long he'll be. Then if I shout up the stairs for him he'll get huffy that he's only doing x, y, z and why does everything have to happen immediately.
