Just had a few. So, one day my brother and I were leaving to go some place. I brought my DSi, while my bro was looking for his. He seriously spent like half-an-hour until my mom said it was time to go. So, on the way, my brother had this thought where he left it at my aunts house, who has childen that can possibly ruin his DS. So he was freaking out. When we got home, he took like so long searching for it. That wasn't even funny! So, I soon just finally started to chip in and help. It took me only a few seconds to find his DS (XD) Where was it? On a shelf right next to the place where he does his homework.
The same thing like that was happening to me once. The day before some TCG tourney, I was preparing. So, I was getting ready to put my deck in my backpack, when I noticed, "Ummm.... where is my deck!" I searched everywhere for it, since that deck was amazing. And I didn't want to change. So after about an hour, I was just about to explode. And then I found it in my backpack, where I put it in -_- Wow... do I have a bad memory!
