All Time Low

So I just walked up to my dog to bring her inside and she laid down and turned on her back. She does this quite often- you all can tell me if it's a normal dog thing or if it's weird. But either way... can you imagine if we did that? Like someone walks up to us and is going to chastize us for something we did and we just lay down and put our tummies up like we want to be petted? It would be interesting to see their reactions. ~bj
