yes and no

"yes and no " means partly agree and partly disagree". We use it to answer questions and show that it's not completely"yes "or"no".For example,When I asked her,"How's your holiday?" She answered,"Yes and no." "What do you mean? "I mean I enjoyed my holiday a bit, but there was still something wrong with it." Another example," Is it good for you to eat meat ?" " Yes and no."
