My favorite senior asked me if I had seen the little girl at work. She wanted to help me catch up.

It is possible that she is testing you because she likes you, but she is afraid that you don't like her, so testing you will make her feel better. If you want her to know that you like him, don't say "no, I like you" at that time, so she will think you are joking and won't believe you. You should express your meaning directly or indirectly when she is calm with you, or when you are alone.
