Ask her something you know she will know, like advice on your homework or your clothes, whatever seems appropriate. Once it has become normal for the two of you to speak occasionally, ask her about her friends, the ones that say she likes you. Tell her they said things about you you weren’t really sure of if they were serious or joking. Do they often joke about things like people being in love with others?
