I've only met one other blogger before.
It was quite a while back. One day at work I was working the fitting room taking people's things and getting them into rooms. Then all of a sudden there was a familiar face in my line, just waiting to be helped. I was shocked, a little confused and almost starstruck. With it being really busy at the time I just quickly helped her into her room. Then I was like 'I'm being crazy, I should just say hi and tell her I like her work.' So, when she returned the items she didn't want I (was pretty sure I) sounded like a huge creep and said something along the lines of 'I just wanted to let you know that I know you're Blooming Leopold and I really love your blog!' Luckily she didn't act like she thought I was a weirdo and was perfectly nice and sweet about it!
