忘记

If you have lots to carry, don't travel alone
If you don't like saying goodbye, don't say hi
If you don't like ending a relationship, don't start one
If you want to forget, bring everything back to zero.. to the start.

有太多行李就别单独旅行
不能够离开就不要接
近舍不得结束就别开始一段感情
想忘记就要一切归零

Ok, I try my best to translate.
It's part of the Lyrics from the song.
