Great stuff. Adding extra pointers.

Body Check -
When to people are really making a connection, they tend to mimic each others' gestures and voice levels.

Signs your date is going well: Watch to see if you find your date is mirroring your gestures, a strong indicator that the date is on-track. Another positive signal is if your date is leaning towards you as you speak. Other good signs to watch for including nodding and tilting the head to the side as you are speaking, an indicator your date is interested in what you have to say.

Danger sign: If your date is crossing his or her arms while you're speaking, it is generally a sign of resistance or anger.


Flirting or Faking? -
Key signs your date is interested include smiling, extended eye contact and biting or licking the lip. (theirs, not yours... duh??) Another key signal for both sexes is low-level non-sexual touching such as a brush of the elbow, arm or leg.

Signs your date is going well: The classic flirting move is the crossing or uncrossing of the legs, brushing their hair, grooming each other.

Danger sign: Keep an eye out for flirting that isn't accompanied by other "I like you" behaviors - this can indicate a purely sexual, not romantic interest.

And you're saying "be yourself"?

Depends on whether you want an ONS or a long term FUBU.
