I went away for a week to fuerteventura and in my possession in my handluggage on the way there was 1 carton of ready-made milk that I forgot to dump

but no-one caught on.....but on the way back was worse
we packed in a real hurry on the friday, everything went in everywhere trying to fit in all the pressies but on unpacking my flight bag I discovered I had 3 cartons of ready-made milk and a first-aid kit with scissors in it

I nearly died and it just made me think how come no-one found them, Is security round an airport not as tight as we think?
It would be interesting to hear from others.
