Lesson Learnt: Never Assume

Last evening after dinner, Greg came to me and said he wanted to pass motion. I brought him to the toilet and put him on his kiddy cover over the adult toilet bowl. When he heard a "thud" sound,

Greg: Mummy, I passed out one already you know. Can you hear that?
Me: Yes. I can hear it.
Greg: Mummy, can I come down and see my poo-poo in the water?
Me: Well, ok..
I helped Greg down and he went "aaaahhh" when he was watching his faeces.
Me: Come on Greg, enough. Time for Mummy wash your backside.
Greg: Ok..
Greg walked into the shower area and squatted down. After washing his buttocks, I went to wash my hands with dettol at the washing basin. I noticed that he was still squatting at the shower area.
Me: Hello Greg. I have finished washing your backside and you can come out already.
Greg: Oh... ok.
Greg walked out of the shower area, and it's only then I noticed one cute lump of faeces on the floor in the area where he squatted.
Me: Har? You poopoo again?
Greg: Mummy, I never say I finish poopoo just now... Mummy also never ask me..

Well, what he said was so innocently true. Greg had only requested to come down from the toilet seat to have a look at his faeces and he didn't say that he has finished poopoo-ing. Sigh.. I guess I have also overlooked and assumed that he has completed doing his "big business" then... I should have asked him... aiyo...what a mess he has created but it isn't his fault, is it?
