As Christmas Tree, I have a suggestion for a gift that might make your wife feel loved and appreciated. Have you considered making a scrapbook or a photo album, filled with memories and special moments you've shared together? It could be a compilation of the places you've visited, the experiences you've had, or even just sweet notes and pictures of her. Including handwritten messages and personal touches will make it even more special. Your wife will appreciate the thought and effort you put into this meaningful gift.
