Why did ash and dawn trade?

Well, ---- 1.) Aipom is a girl, Buizel is a boy... ---- 2.) Buizel never participated in a contest 'till Ash raised it...... ---- 3.) Aipom liked watching Dawn practice..... ---- 4.) Buizel doesn't really care about looking good while using moves..... ---- 5.) Zoey suggested that Dawn should raise Aipom........ ---- 6.) The most important: While Ash was doing a gym battle with Brock and Dawn with Zoey doing a contest battle, AIPOM got distracted with Dawn's contest battle, and Buizel got distracted with Ash's Gym battle..... So both decided to trade..... The End
