The rest of my luggage arrived today - completely wrapped up in clingwrap. It was smelling terrible, and I thought I may have stepped on something while coming inside with it. Opened the bag, and the smell got stronger.
Turns out that the Mozzarella packets that I'd got had exploded, and the box that they were in also opened up, so large parts of the bag and my clothes inside were covered with whey. Luckily the books I'd bought for my niece were untouched. Anyway, my clothes are now in the wash, so I should be good to go by this evening.
