You're a very diligent worker, and you seem to have taken the Virgo concept of structure and applied it to every corner of your life. Part of this comes from desperately wanting security, which you think comes from meticulous attention to detail (and often you're right!). But don't completely forego a social life.

Individuals sharing this birthday sometimes feel underappreciated for their efforts. It's a hard pill to swallow for you to realize that the extra work you've taken on dutifully has become the “norm” in other people's eyes.

Partnering with this Virgo is a very surprising and expressive interaction.
