Do not stand on the scales

My FIL brings his scales back from the wet market once in a while. My kids love to stand on them when he's asleep. I often tell them not to do that. But you know, kids are kids. How do you expect them to understand, right. I think he brought the scales back as he needs to send them for calibration. I wonder when will my FIL retire? But if he does stop going to the wet market one day, he might be bored home all day. Had better have a word with hubby and see if he can come up with something to keep them two old folks busy. If not, they might become senile fast!!!
