I don't remember where I saw this idea, but I like it: preserve the beautiful flowers you get by taking pictures of them. This week I got two bouquets when I said goodbye to my job*. The white one is from my bosses, the colorful from my co-workers.
*my job outside the house that is. I will be working with T. in his IT-business. I already was, actually, but his business kept growing and I kept running out of time ;-)
