I'm gonna be using this spell http://www.spellsofmagic.com/spells/love_spells/friendship_spells/1418/page.html

I'm supposed to write what should the friend be like. So , do I have to use just one word for a characteristic. For example, "trustworthy", or I can write "someone I can trust" ? This can be said both ways, but if something can't be wrote in one word, is it ok to write it like that? :)
