I too think that doing nothing is probably the best option. In my case though, we have 3 little ones that notice things like that. My middle one proclaimed over Christmas dinner to the extended family that my W didn't get me anything. So they notice. I'm thinking working with them to make sure they're doing something for her, and then just a big box of candy or something with W and kids named. But I'm struggling here also. Would love to do the, I'm sorry, meaningful, I love you card thing but I guess we all know how well that will go over.
