A baseball glove. A school bag. A feeling of pride that I got for the first time when I was a child. A leather-covered sofa in an airport lounge where we spend a few times before the departure gives us a relief and a bit mixed emotions by reminding me a catcher's mitt. The relationship of trust with the leather wristwatch which I check every day after washing my face. The memento of leather comes back at an unforeseen moment.
