Step 1:
Greet him/her politely with your sweetest smile.
Step 2:
Start conversation with your best words. Make sure she's not boring!
The third step is the most important step among above steps where this step will show you either you are success to tackle him/her or not.
Step 3:
When both of you are done with the conversation, one of you will move away to leave. Here is the important tip; the best way is that you let him/her go first. While he/she is walking off, YOU! quickly put your leg after his/her leg. Then, he/she will fall like a Durian. It's a TACKLE!
Well done! You're already tackle a guy or a girl only using 3 steps above. It is SO easy, right?
