Wherever your partner is, they'll appreciate any mail that they receive from family and friends, but if you send them a box of their favourite goodies, they'll love you for life. Care boxes don't only show that you're thinking about them, but it also gives them something to look forward to. This is the perfect time to get carried away if you want to too; it's totally fine to wrap up presents and send some nudes of yourself... Do it old school with polaroids, but keep them classy.
