AIBU to cringe and feel deflated on xmas morning when the kids (we have a few, aged 7-14) dive into the presents like feral animals, rip open the wrapping on their gifts, not even properly look at the gift before moving to the next, sometimes not even finishing removing the wrapping paper. No thank you. No comment about the gift. Just manic, uncivilised chaos. :( Then disappear back to their rooms.
