7. Grandma call
If your grandma is alive and well, you could say a little lie about her or some other elderly member of your family. Just say that your grandma/great-uncle/old aunt that never got married called you this morning and sounded rather incoherently. Naturally, you feel worried, and you feel like going to check up on her/him. It makes you look like a perfect caring grandchild. A true philanthropist, might we add.
