First and Last
I have three younger sisters. When growing up, having this number of children in the house meant that all snacks- crisps, biscuits, sweets, etc- came in multipacks.

A curious ritual grew up around these multipacks. They would sit, unopened, for quite a few days after purchase. This was because, no matter how many packets of crisps or whatever each person actually ate, when all the packets had been gobbled by the end of the day, it was always the "fault" of the person that had the first packet. Looking back, it seems as bizarre and senseless to me as it probably does to everybody else, but at the time, it made perfect sense.

Somehow, this practice later evolved. Being the first to open the multipack was still bad, but to take the last packet- that was much worse. Because now it really was your fault that all the crisps had gone.

This eventually became quite farcical, with a 24-pack remaining unopened for weeks, or a single custard cream left at the bottom of a packet, untouched, because nobody dared to eat the last one.

This ritual has now, of course, ended. Though I do still feel an acute guilt upon either opening a new multipack, or eating the last biscuit.

Surely
That's an easy one, you carefully cut the bottom of the pack open and commence removing the contents while resetting the pack carefully bottom first in the cupboard. By the time anyone spots it's started it's WAY to late to apportion blame - I may still be doing this after more than a decade (works with cans as well).
