By accident. Long story, but I accidentally took this calculator. But then I gave it back the moment I noticed...Seriously it was by accident! Why would I want a calculator?!
Do you go up the down escalator and down the up escalator in the mall or just go into stores to ride the escalators? (I do! My friend and I walked into Barnes and Noble, went up the escalator, walked over the other escalator, went down, and left. o.o)
