Coding panic

I spent all day coding and it was fairly horrible. Thankfully I was booked into formal for dinner and the food was incredible - melon to start, duck for the main, and lemon sorbet for dessert! 

I am hoping that I can finish my coding early tomorrow (I have a deadline for Thursday) and go on a run after work. However, I just tried to do a bit of work at home and can't find the two files I need on my memory stick (where I was sure that I saved them). I am fairly confident of them being accidentally saved onto my lab computer though - I remember pressing save at least 20 times, and it's unlikely that my memory stick would break and delete the only two files I need. Let's hope so anyway...
