What's got into me?

My Cheng is potty trained daytime at home but not bedtime yet. His nanny, somehow is a hygiene freak. She will put on pull-up pants for Cheng for fear that Cheng will pee on the wall where she places the potty, simply because Cheng cannot aim properly. That's what she claims. The pull-up pants are thin so it's used only daytime and Cheng doesn't poop in it. He is smart to know that he just has to put it on at her place because the nanny will nag. Everyday after I pick the kids up, the first thing he does is to take off the diaper when we reach home. We went for grocery shopping last night. I reminded myself to buy night tapes for him since the pack he is using now is going to finish. I looked at those diapers on the shelves, was happy with the pull-ups price, so I grabbed and put it in the cart. When we unpacked our stuff at home, I told hubby we still have to get a pack of night tapes for Cheng because I couldn't find it at the mall with reasonable price tag. Looking perplexed, he asked, so what did u buy just now? Since Cheng is potty trained daytime and he is not going to the nanny anymore, what are you going to do with the pull-ups? Ah-ha, I totally forgot that we do not need pull-ups anymore from now on since Cheng will start kindy next week. So the RM30 last night was probably not-a-wise spent but on a good cause. Hahaha...
