Quoting JiLLiAN.:" Aw I asked him yesterday when he was gonna start wiping his butt and he just doesn't care. He can ... [snip!] ... He can do it. He's just lazy. You should just tell her you'll do it for her from now on. Maybe she'll do it herself then."
When my nephew was 3 1/2-4 he would scream, "(insert name here) come wipe my butt!" from the bathroom. So my sister finally told him that he need to learn to do it before he started kindergarten, he said, "No I don't." So here is how the convo went after that.
Sister: "Then who's going to wipe it for you?"
Nephew: "My teacher will."
Sister: "No she won't, she isn't allowed and she can't wipe everyone's butt for them."
Nephew: "Then I will get my friends to do it."
