Why do electric charge move to another location?

Classic textbook example : Rub a balloon on your hair, then the balloon sticks to you hair because they are oppositely charged.

But why do charges transfer in the first place? Are all balloons positively charged and is my hair always negatively charged in the first place and hence from rubbing they gain/lose the charges?

If I have a balloon that is neutrally charged, this can't happen right?

Is being negatively net charged means there are more electrons in the object?

    "But why do charges transfer in the first place?"

    Electrons have a greater affinity for the balloon than they do for hair.

    "Are all balloons positively charged and is my hair always negatively charged in the first place?"

    Generally, no.

    "If I have a balloon that is neutrally charged, this can't happen right? "

    If you rub the balloon against your hair, it will acquire a negative charge.

    "Is being negatively net charged means there are more electrons in the object?"

    Yes -- there are more electrons than protons.

    Hope this helps!

      Your logic is faulty. And what does " this means there is a indifference of charges on both objects" mean? These are the right answers.
