Q: M: Why do you have an umbrella with you? It's not supposed to rain today, is it? ,F: No, but it's supposed to be very hot.

I always get super red if I haven't put on sun cream.
(A) M: Do you never put on sunscreen because you are not easy to get sunburn? (B) M: Since you are so easy to get sunburned, why don't you bring an umbrella? (C) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (D) M: You don't even know the first use of umbrella. No wonder you don't have an umbrella.
