In other news, having nothing at all to do with nalbinding: My little lemon tree has actually decided to make a bud. Yay! It came with a lot of flowers and buds when I bought it, but only made the one lemon that was already on it when it arrived here. Afterwards... nothing, nothing at all. So I'm very happy that it seems it now has remembered its job. Hopefully the flower will not remain the only one, and there will be a few fruits, too!
