Who do you have a hard time taking seriously?

Hello Friends, Some boys often ask me this question "Who do you have a hard time taking seriously?" I don't know they love me or not. I don't know that I'm their crash or not. I don’t know why they are interested to know about me? but I feel that they are weak. I don't know what is the answer to this question? for this, I always try to talk to another topic. So I need to know the answer to this question. Please, someone, help me. My question is -  Who do you have a hard time taking seriously? Thanks.
