Birthday Present

I spotted a bargain - a lens I have yearned for for quite a while and my lovely wife said I could have it for my birthday on the condition that she would hide it away until my birthday. The problem is my birthday isn't until early May:-O I don't know if I can last that long? I wasn't even allowed to take a picture of the lens itself, just the box! I will need all your positive thoughts to get me through the next few weeks
