i'll have to agree w/ the engagement ring. I want you to feel the same way about me that I do about you so therefore when that time comes I know that we will both feel ready to take that next step.
But other things...
...an expensive car (a 2000 honda accord 4 door will do me just fine

)
...a million dollars
...play station w/ games
...coach bag
...kenneth cole shoes
...clothes from jcrew or ann taylor
...anything from Pier One Imports
