I need help..-_-

I have a problem...
I KEEP LOSING MY PENCILS!!
I will have it one minute, and lose it the next! I'll put it in my backpack, look inside for it later, and not find it. Then days later I find it! In my backpack!
hoặc I could be sitting doing school on the couch. Put down my pencil for a second, and when I go to get it again, it's gone! I look everywhere for it! I lift up all my books, stand up and look where I was sitting, EVERYTHING!
What do I do?
My pencils hate me!! D;
