Wanna know if someone really LOVES you or not?  Here's a simple test . . .

Just YAWN in front of them.  If they yawn back . . . they love you.

You know how yawning is contagious?  A study out of Italy found yawning is ESPECIALLY contagious between people who love each other.

So if you yawn in front of your parents, your grandma, your siblings, and hopefully your significant other . . . they SHOULD yawn back.  And the QUICKER they yawn back, the tighter the relationship.

That being said . . . the people behind the study say it's not 100% accurate.  So if you yawn and your boyfriend DOESN'T yawn back, that's not an offense worth dumping him over . . . it's just one failed test.   (MNN)
