I need to use at least five different pronouns in my sentences. Can you help?

(I) recently asked (my) sister about (her) use of credit cards. (She) told (me) that (she) uses it to make everday purchases. (I) asked (her) if (she) was making any type of payment on them. (My) sister told (me) it was none of (my) business. (I) left it alone and told (my) fiance that (they) will eventually learn about being in debtthe hard way. (He) agreed with (me).

You used these: I, my, her, she, they, he

In addition, "it" is a pronoun.

Your sentences are fine.
