[sparkly]

[Orange_County]

[ghost69]

they go out of the way to say hi.

i go out of my way to say hi and talk to both guys and girls. so that can be misconstrued. actually, lots of guys thought i was interested, but i was just bored and looking for chitchat.

[ghost69]

yeah, so you do it to everyone. but it can be obvious.

[Weirdman]

Might be overly talkative with you, or maybe overly shy, if they are normally not shy.

[Altruist]

If they squeeze your butt when they pass you in the corridor...

[ghost69]

if they lick their finger in front of you when they spill some sauce.

[swertyqwerty]

when they are completely ignoring you, that's a sure sign that they want to get in to your pants, obviously!

 

But I think just randomly touching someone innocently (like picking up a piece of lint) while looking in their eye is a good sign, since they are comfortable enough with you to do those kind of things.

If they are not overly shy, then trying to talk to you more often than not is a surefire way. But then again, you gotta pay attention to key signals in the convo.

 

Try to establish a good level of eye contact. Proximity and trust are dead give aways beyond that.

when they say, 'hey you have a fuzzy on your back'. they were checking you out.
