One by one

Sometimes I want to say to my problems for then came to me one by one, not all together like than like to do. If I can give one idea for the flow of problems, I could ask a little door for all then come, all then will try to come together (like every time) but, then will only can come one by one.

In the ends of day I will say 'It's over now', and then say 'See you tomorrow'. Day by day.
