Jack in the Box

I solved my transport problem: I bought so many useful books at London's bookshops that I my small hand luggage bag won't be suitable to take this collection home. So I bought a bigger suitcase, hard case, medium size, in pink for better recognizing on baggage reclaim belt at the airport. The small bag fits into the suitcase perfectly, so I still have only one piece of luggage to carry. For the scientifically biased among you, here's the math formula for solving the transporting problem: 1 plus 1 is 1. Haha!
