Max has a pretend big giant

Max has his very own pretend big giant. He has seen big giants on Mickey Mouse Club House and on Harry Potter and he apparently really likes them because he now has one of his own. He will be playing away and stop what he's doing to tell me that there is a big giant near. Then we have to be really quiet so we don't disturb the giant. Its really funny. A couple weeks ago we were playing with a ball in his room and it rolled out into the hallway. I told Max to go get it and he says, "shhh, mom there's a big giant out there." He then tiptoes out into the hallway and retrieves his ball, comes running back in and then laughs and says, " whoa big giant". I wanted to laugh but I didn't want him to feel self conscious about his creative imagination. I wonder what he will come up with next?
