'Spring cleaning' my drawers

I decided to do some housekeeping for my drawers yesterday. After I came back from running, I opened up some of my drawers where my bills were kept. Household bills like the telephone, utilities, credit cards plus some other miscellaneous things. I only kept those from 6 mths ago till the latest ones while I threw out the rest. I was telling Angela that if I had just summed up the total amount incurred for 12 months, how much would the total amount add up to. Anyway, I looked through them before tearing them up into pieces and putting them into a plastic bag before disposal. Initially, I thought of bringing them to school and putting them through the shredding machine but I reckon that might be too time consuming considering the fact that I had kept some invoices that dates back to the year 2005! Now that tells you when was the last time I did 'spring cleaning' as far as my drawers are concerned.
