I want to know how the xylenes (o/p/m) are meta or ortho/para directing?

Ortho-xylene is 1,2 Dimethylbenzene.
Which methyl group of the o-xylene? What kind of reaction? Electrophilic aromatic substitution?
Each methyl group is considered an activating Ortho/Para director, but work against each other when located in the ortho position.
For example: Bromination of o-xylene yields 1,2 Dimethyl-4-bromobenzene. The Br is para to methyl-1 and meta to methyl-2.

Methyl is a weakly activating o,p director in electrophilic aromatic substitution. If you plot out the positions activated by each methyl in o-xylene, you will find all of them activated, so I don't think you can say whether it is o,p or m.

Doesn't the o in o-xylene stand for ortho?
