Likewise - I do the outward [*] packing at NB Towers.
Mrs NB is responsible for tickets/money/passports.
I usually distribute a few items of each other's clothing between the two cases in the event of one going AWOL on the outward leg as well as having the ability to pack stuff in smaller spaces more efficiently.
However, a further consideration for the upcoming trip is the increasing number of items that have been delivered to NB Towers, courtesy of Junior NB and the large south American river company. Apparently, we have been tasked with mule duties for stuff that isn't readily/cheaply available in UAE. A warning message was issued on the family Whatsapp group earlier to the effect of "no more deliveries, or they get left behind"
[*] "Although I will carry it, you're responsible for packing your own case on the way home and if your stuff doesn't fit, don't come looking at me and my half-empty case"
