My wife and I got a diary type thing that we write back and forth for all birthdays, anniversaries, mother and father days, etc. this really prpts is to write more rather than let the card say it all. We have gotten to documenting things that are going in in our lives at the time and the plan is to give it to our kids as we get older or even after we pass. Even now when we read back through some older posts, it has been pretty funny with details that probably wouldn't get documented otherwise. generally no gifts for valentines or anniversaries but sometimes. Also a way to acknowledge the holiday without giving to the greeting card industry.
