You are right and wrong.

Yes, when you pull something, you are pushing on it too. But

that doesn't mean "when you pull something you actually are pushing on

it". That just means "you must push something while pulling it".

Look at my scheme below.



       +--------------------------> PULL

       | 

       v PUSH

+--------------------+

|    OBJECT          |

+--------------------+

       ^ PUSH

       |

       +--------------------------> PULL



Why must we push something while pulling it? Because we must

make a friction between the puller (say, our finger) and the

object. Have you learnt the vector and the Newton laws?

I'll tell you more if you have learnt them.
