Create a box filled with sealed letters. You could do this alone or with a group of friends. On the outside of each is a particular need or topic to be addressed. Inside the envelope can be photos, memes, advice, a short note or letter, a coupon for a drink, a cookie, a doughnut, a gift card to their favorite store, a suggestion of a particular movie to watch on Netflix. This takes imagination, but the goal is to let them know you are aware they will have these days and you want to be a source of comfort to them on these days. Here are a few topic suggestions:
* Open When It's Your Birthday
* Open When it's Your Loved One's Birthday
* Open When It's Christmas
* Open When It's a Rainy Day
* Open When It's Been a Hard Day

* Open When You Need a Good Memory about Your Son (or whoever they lost)
