Nothing has confused me more than these two words. I'm always doing okay translating, but when I come to something preceded by "lo" or "se", I instantly lose track of what the phrase is.

Oh and sorry, one more thing to. Is "le" just another way of writng "su"?

Hi Illathanyou!

Well, we´d better have a context, to give you a better explanation.
Right now, I can just tell you part of it...

"lo" is usually a direct object, like in the sentence. Call him: Llamalo.
"se" can be an impersonal use, it can be passive voice, it can also be a reflexive pronoun, it can also be part of a verb, etc. The house was sold: La casa se vendió (passive voice). It is said in this town... Se dice que en esta ciudad... (impersonal use)
"le" is usually an indirect object. I gave the papers to her. Le di los documentos (a ella).

Give us some context and we can help you more, rgds!
