Say and tell can sometimes be confused. Say means decir, and tell means contar. Say goes before a personal object pronoun, and tell goes before a noun:

say + something           tell + someone

Say goes before these words:

add, confesion, remark, announcement, agreement, statement, complaint,
claim, mention, pledge, declaration, reply, admit, deny, swear, anser, explain

Example: He said his confesion to the preist.

Tell goes before these words:

convince, inform, assure, promise, teach, notify, remind, warn, secret, a story, to do something

Example: He told me a secret.

* Some words that go with tell don't have to have a personal object pronoun after
it, for example: ...a story, ...the truth, ...a lie.

* It is possible to use say with a personal object pronoun, in which case you use to; but this is only used when you are trying to stress a point, for example: I said to him.

1) I told him I wanted to buy his car.

2) She said she agreed with me.

3) The police told me I would have to pay the ticket.

4) I said I didn't want to go to Vina de Mar.

5) He told her he was in love with another woman.

6) My grandmother used to tell a story about a green goblin.

7) John said he was hungry.

8) My mother told my father to pick me up after school.

9) She said she wasn't tired.

10) George Washington never told a lie.
