Two years ago on my way back from Italy my suitcase got lost in the airport, and they didn't return it to me when I arrived back in London. I thought I was a person that is relatively detached from material things, but when I realised that my clothes (and all my Christmas presents) were gone, I realised how important they were to me!
A week went by and I kept calling the airport, and they kept telling me they couldn't find the suitcase, and that I needed to wait. I had a few things to wear left, but definitely not enough for 2 weeks. So I waited a bit longer, and after a few more days I went ahead and bought a lot of new clothes. That was refreshing, but I was also still hoping to get my suitcase back.
In the 4th week, when I had almost lost all hope of getting my suitcase back (i.e. was more detached), the airline company finally rang me and said they had found the suitcase! It was quickly sent back to me, and the new clothes that I bought were 80% refunded by the company. So everything turned out better than I ever expected.
But still, that sudden realisation of how attached I was to my clothes remains with me to this day! It makes me wonder: what else am I unconsciously strongly attached to?
