you're born on the 21st of may yes? does that make you a Gemini?
Actually, it makes me both a Gemini and a Taurus. May 21st is a cusp day, that’s why you’ll see some Zodiac calendars that say May 21st is the first day of Gemini, and some that say it’s the last day of Taurus. I typically think of myself as a Gemini, though.
I wish I could offer you a picture or something like many others seem to be making, but nevertheless, I feel inclined to wish you a happy birthday! I'm sure you'll probably get a hundred people wishing they could draw something for you, but as a fellow student of psychology, I think we can both agree that it's the thought that counts. ^^ So happy birthday, and I wish you the best and look forward to your future work!
