I always said I wouldn't - I've been squeamish about needles or piercings or anything similar since I was a teenager - but I found I've lost a lot of my fears in the last few years. I've worn clips for years and I've always loved them. It seemed like a good decision.
The downside to being almost thirty before you pierce your ears is that you inevitably end up feeling like a child. It didn't help that I went with Lucy and Addy lol! ;) (Although it's totally a special memory that will be fun to tell them in the years to come - that we all got our ears done together.)
