Ring! Ring!
Just as Anna was thinking, her phone rang. She quickly picked it up.
"Yes?"
"Sister Anna, have you prepared thicker blanket? The temperature is dropping quite fast at night," Dylan's voice could be heard from the phone.
"Don't worry, I have prepared blanket. How about you? Do you need blanket?" Anna asked back.
"I have blanket." Dylan was sitting on his bed in his room. He also didn't expect the temperature to drop so quickly at night. When they went to bed, the temperature was still at 25 to 27 degree Celsius, a normal temperature.
It was instead a bit hot for some people, so many people might not even want to wear any blanket when they were sleeping.
For Dylan and Anna, blanket is necessary.
So even if it was not very cold, they still use a relatively thin blanket when they were sleeping.
"Good." Anna sighed.
