Maybe we should have a contest to see how impressive our applications were. ;D Ours was 2.2kg, 5lbs. By far the largest part was the relationship proof which included chat logs, pictures from trips I took to Philippines, the wedding, honeymoon etc... Though we did keep it quality over quantity, like printing only 1 out of every 20 pages of chat logs (there were nearly 1750 pages), only 10-12 pictures from each trip or event, but all original receipts for things I purchased in the Philippines and of course the boarding passes and stuff.
Anyone else get excited for a moment when your phone dings, wondering if that's an e-mail from CIC?
