Avoid eye contact... it works

i've come to realise that when someone avoids eye contact with you it means they like you.

Step 1: Do NOT make eye contact with him/her but use appropriate expresions on your face. E.g. if they say something funny, still laugh.

Step 2: Eventually they'll look away. Whilst being aware of this, stare straight at them until they notice...

Step 3: When he/she turns around, look down fast.
