You make a few comments to your wife on Sunday morning and it becomes obvious she had forgotten it is your birthday (but not admitting she forgot). A few minutes later, while you are in the bathroom, you hear the front door open and close. When you come out of the bathroom she is back and presents you with a selection of candy bars she obviously just bought from the Duane Reade across the street. She pretends she knew it was your birthday and says something lame like "hey, I know how much you like candy" as she hands over 4 chocolate bars.
Would you get mad or would you just let it go for shalom bayis' sake?

) and that would be a waste of money.
