Robby if you do it right, it should go something like this.
A get machine for wife. say I love you hon this shows how much.
B get her hooked on it, she likes coffee
C remind her how much you love her and have learned about 'coffee' and how that machine is 'lacking, but.
D re remind her, that since you love her so much, you are more than happy to get a (insert dream machine here) so you can make her REAL espresso
E emphasize it's for HER you are making this gesture of love. *who says you need diamonds to get #@3#$@ you pull this off right and an espresso machine might do it
plus YOU get to keep the machine.....
Sounds good in theory...
