Input: Text: i'm planning on proposing to my girlfriend so naturally i've done all my research on the 4cs and all that good stuff. my friend is also planning on proposing to his girlfriend and his father works for a national jewelry retailer so he knows everything you could want to know and more about this stuff. so he is showing me some different options and prices on his laptop. 

unlike myself (i have talked over my intentions with my girlfriend and am shopping around with her), my friend is planning his proposal to be a surprise, and actually already has the diamond. unfortunately, when he went to show her something the next time he opened his laptop, it was still on the tab with a list of all these different diamonds. not only did that ruin the surprise but the page wasn't even up for his research since he had already bought it!
