Valentines Day Soul Mates?

Funny story, how do you know you are truly with the one you belong. For me I think this is a good indicator. My wife and I just traded Valentines Day Cards, and when opened up........you guessed it, the exact same card. To make things even more ironic is that they were purchased at 2 different Hallmarks, more than a month apart, and the card is gender specific. Meaning in the text of the writing it actually says "your wife", but when I read the card The rest of the text was so appropriate that I changed mine to say "your husband". I am really astonished that we could have picked the same card for each other, and got myself thinking.....has this ever happened to anyone else? Anda, what do you think the odds of this happening are? Hope everyone else is sharing a good Valentines Day with their significant other.
