Rex and Molly are the same. That girl is an actress - i swear she must say to Rex 'Mum's here, get your straight face on' but he can't do it. Even if he's done nothing, when he knows something is not right & he could potentially get in trouble for it, he does this slinking action with his ears pinned back, eyes fixated on me at all times. Molly on the other hand can act just as lively as ever giving away nothing. Eventually it's Rex that will give them away lol. Unless it's something big - like landscaping my backyard then she will give me the 'look' because she knows there is absolutely no way in hell she can get away with something like that unless i was blind!
