I remembered when I was younger, and mom and dad told me i was getting a little brother, I was really excited. after all these years of getting pushed around by Rodrick, "I was definitely ready to move up a notch on the totem pole." Could you please help to explain the sentence I marked? I could not figure it out at all. Thanks in advance. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 125.229.88.182
