Mamta has been focused on nuts lately. Not the kind of nuts for which Berlin is famous, but rather tree nuts — acorns and chestnuts, mostly. Her interest, or dare I say obsession, came on gradually. I noticed that getting from one place to another in the city seemed to be taking longer, and realized that it was because Mamta was constantly stopping to gather nuts. She usually hands them to me for transport in my pockets or man-purse (aka bike messenger bag). Shiny brown horse chestnuts are her preferred quarry, but she delights in finely-shaped acorns as well. I began to wonder what was motivating this passion of hers, and why, for that matter, were there so many nuts lying around anyway?
