Walking on water

So I come down the stairs last night and there she is................................. standing right in the middel of the glass coffee table . Now I have no doubt that she is smart and agile enough to get up there but how she didn't break right through the thin little piece of glass with all her 4 months of girth is beyond me. When I yelled at her she turned and looked at me as if to say, "Look Ma, I'm walking on water". As I came closer she immediately turned and jumped off the table and ran........as if to say" OK, perhaps you aren't amuszed."
