Snowing all the time

It's crazy because I don't even know how you came to be so important to me. It's like watching a snowstorm; You see all the flakes falling, but you don't realize how quickly they're adding up. Each one just as small as the other, you think nothing of it and just keep watching. Then suddenly, everything around you is covered in snow and it's all you can see. All these things have now added up, you're my snowstorm.
