in front of the grandparents, really?!?

So, Grandma & Grandpa B were over last night to visit...and the boys were in FINE form. D was throwing pillows, L was whining that he could not hear the movie that was playing (that he should not have been watching anyway...) D would chase L around and they would scream. They both thought that they were (as L put it) 'thirsty to death'. Really? Arg!
