three o'clock
Things like that ... . Gee ! If I do n't get to bed I 'll be late at the office in the morning ! '' Mr. Wrenn lay awake till three o'clock . Monday morning he felt rather ashamed of having done so eccentric a thing . But he got to the office on time . He was worried with the cares of wealth , with having to decide when to leave for his world-wanderings , but he was also very much aware that office managers are disagreeable if one is n't on time .
