Are there certain standards that something must meet to be considered magic(k)? For example, A child making a wish on their birthday candles. They are wishing, and putting some amount of energy into it...but is it magic(k)?
Generally we think of spells when we hear 'magic(k)', but are there not things which are magical that aren't spells? Like the changing of seasons, or an undying hope. So, my question is, what is to too 'small' to be considered magic(k)? Is there any thing to 'small' to be considered magic(k)al in nature?

Opinions, please.
