Junk is something you've kept for years and throw away three weeks before you need it.

Before I came to Singapore, Dad gave me many photo copies of all my documents. I kept them for more than 10 months and did not really use them at point of time. I thought its better not to keep junk at home and finally decided to throw them. Just weeks after I threw all the photo copies, I was asked for my passport photo copy by Surya for the house contract. I was not sure where near my house this can be done and hence I had to wait for 2 days to go to office and then get the photo copy done.
