I'm not the girly type. I like dark blue/black themes with white wolves and a bright perfectly round moon on a clear night type of person. However, I saw this on your Firefox themes and added it. Loved it so much I followed your link to this wallpaper. Glad I did. It's cheery and up beat and just makes me happy today. It puts a smile on my face which is so important. So thank you very much for making me smile today! ~frankiebluej
