Basically. People ship Dawn and Ash because:
1. They high-five a lot
2. They are supposedly best friends.
3. Couldn't really care less about this sh*t and about Dawn so I didn't think this through.
But, thats just the beginning of getting it wrong. Really wrong. más wrong than, say. that lame sum in Math which doesn't really have an answer.
The fact that they high five a lot shows that Ash is really comfortable with his hands contacting Dawn's. On the other hand, remember the time when Ash and Misty's hands accidently touched while trying to find Totodile's poke-ball? Misty blushed and on closer inspection of the reactions, Ash was equally awkward about the contact. Which shows that he was feeling shy about coming in body contact with Misty. Its a fact, tu can cross-check por watching the episode again. (Only I cannot give tu the ep. no. I don't remember myself).
As for the 2nd point, Have tu heard of 'Friendzoning: Level Pokemon' ? Ash pretty much friendzones all girls, Misty wasn't as friendzoned as Dawn was. o Iris is- he really doesn't care about how they feel for him. Plus, Misty is a más closer friend of Ash's than Dawn ever will be.
The proof of the above statement is the fact that..
Did Ash cry when he departed from Dawn's company? NO! He didn't. He did not even have a tear in his eye.
But, if you'll recall, Ash genuinely cried after Misty left.
I'll rest my case. Mind you, this has been written after más research than I've ever done. tu can go back and watch the episodes...
