Is it normal to keep birthday cards?
Yep.Totally normal
Yes, it’s normal to keep birthday cards. They can feel like little reminders of people and moments, though plenty of people recycle them once they’ve read them.
Birthday cards can be surprisingly sentimental: they hold someone’s handwriting, a personal message, or a memory of a particular year. Lots of people save their favorites in a box or drawer, even if they don’t look at them often.
Others prefer not to keep paper clutter, and that’s normal too. You can keep the cards that mean something to you and let the rest go—there’s no official card-keeping rulebook.
