I don't love you like I did yesterday 该怎么理解?
Well when you go So never think I'll make you try to stay And mabay when you get back I'll be off to find another way And after all this time you still owe meYou are a still a good for nothing I am not So take your gloves and get out Better get out While you can When you go Would you even turn to say I don't love you like I did yesterday Sometimes I cry so hard form pleading So sick and tired of all the needless beating So fix your eyes and get out Better get out While you can When you go Would you even turn to say I don't love you like I did yesterday When you go Would you have the guts to say I don't love you like I LOVE YOU yesterday I don't love you like I LOVE YOU yesterday ...
