The 25 year mark is getting to be quite rare in this day and age, so that's really reason enough to celebrate. The official theme for this year is silver. That's more like it, right? Cause there's sooo much you can do with this theme. Apart from the obvious choice of jewelry, the other gifts that you can present include silverware, engraved silver key chains or a ƈ and 5' days vacation at an exotic location (second honeymoon, why not).
But, at times, material things aren't always the perfect choice for the occasion. In the end, it is up to you to decide what kind of gifts you'd like to present to your husband, and basically, make his day. And remember, whatever gift you present to him should be something he doesn't already own and can utilize it on the day or in the future.
