uletmedownandhappy 點解

uletmedownandhappy
= u let me down and happy / u 係 you通俗寫法
= you let me down and happy
you let me down = 你令我失望
you let me down and happy 唔係正統英文. 內容大意係:
你因為令我失望而開心.
廣東話係: 你令我失望, 好開心喇?!

uletmedownandhappy意思就是::
you let me down and happy
你令我失落和開心。

意思應該是
你有時會令我失落，難過。
有時又令我快樂，開心。
