Nothing really valuable, but several sentimental Christmas ornaments turned to dust this past Christmas--one I had for 20 years. They also kept stealing the small, stuffed elephant ornament, which was given to me in 1983 by my Laotian students, to whom I taught English (the elephant is a symbol on the flag of Laos). Luckily, Elly is still intact!
They managed to break two lovely red glass hurricane candle holders I loved (it was a set of three), too. (Christmas was ugly this year...)
My Little Miss does like to steal jewelry, somewhat valuable stuff, but, luckily nothing has been broken...yet...:-)
Every once in awhile, we will be awakened by the sound of glass crashing downstairs!
