Lost

OMG!!! I lost my calculator again! I had lost two calculators in just two months.... How come my calculator kept running away from me? So sad.... I had lost my first scientific calculator (named texas) last month. I like my first very much as i used it since form 2. After that, i get a replacement calculator from my dear. The casio brand which is not familiar to me... I tried to adapt it but before i get to know it much, I lost it again!!! What is happening on earth now?? can someone tell me?
