Have you ever received something special from your Significant Other, but you hadn't gotten or done something for them?

We often get questions here about (usually women) wanting to do something special for their boyfriend on the first anniversary of something. They want to know what they can do for him or give him.

This made me wonder what happened if the boyfriend had failed to see the anniversary coming and didn’t try to so something special in return. How did the boy feel? Guilty? Were they able to enjoy the present? And how did the girl feel if the guy didn’t give her anything?

Have you ever had any experiences in this vein?
