"But mom I'm just sorting..."

Yes, I normally would usually stop this standing on the furniture a lot business, but Alicia was being good, and so darn cute. I asked here what's she doing? And usually I get a "nothing" in a sheepishly voice when she's doing something she shouldn't. But this time I got a proud, "mommy I'm helping you clean." I respond back with well you shouldn't be standing on furniture and you need to be careful.. And I got a "but mom I'm just sorting my movies out and helping." oh, how do I scold her about that, right? So yes, I don't and let her by with a be careful warning...
