Who did that?

It was late into the night by the time we came back from Penang and (unluckily) Kristine was still awake. So, when the saw what I had bought, she wanted some, which I innocently gave her....

This is a very nice biscuit which Kristine loved (for that night)

And the next day, we also discovered that these biscuits
tend to leave a lot of crumbs........ oh-oh. So, I had to mop
the floors again

As usual, Kaelynn was unaware of her elder sister's
midnight snack

Teelseed Oil? I thought I bought sesame oil......
