Shoes are Lost.

hi~
I always loose my shoes. thats so annoying.
last summer my mom gave me a pair of beautiful white cotton summer sandals, but I lost them and NEVER found them back. I'm afraid that they're still in Denmark. (we were on holidays when she gave me them)
and last fall break I got a pair of black boots and when I bought fallstars ending december I lost the boots too. O_O
HOW IS THAT POSSIBLE, and they never come back !! XO how good I search I've never found them back .....
and I don't like that >_>
