Ok so why dont you tell me why you love those types? ;)
For me, well:
Water because water is tough, powerful, unstoppable and can go through any things >:)
Fire because fire is strong, fire spreads fast, leaves long and hard-to-cure damage, moreover, it's HOT :P
Ice because ice is cool, cold, freeze everything on its way :)
And finally Psychic, nothing to say but mysterious, strong and un-see-able >:)
