Because one day all you’ll have are the memories.
You’ll not be able to go visit them or take them to lunch.
You won’t be able to pick up the phone and hear their voice.
You’ll not be able to spend holidays with them.
You’ll see an item in the store that you know they’d love, but there’s no need to buy it because they’re not around to open any gifts.
You’ll still have lots pictures of them, if you’re lucky, but you can’t hug them or kiss them anymore.
Cherish every day. Because you don’t know how many days are left.
