a.Yeah. Nothing but sleep. Tiresome, isn’t it? I should find something interesting to kill time.
b.Actually many things to do. Jogging, chatting, fishing, watching movies, reading, etc., exciting every day.
c. Not really. I haven’t been getting much sleep either. But what can I do? I’ve got to get this work done.
