Acknowledge the situation without dramatizing it. A short, warm note that mentions you're thinking of them and means it lands better than a long, anxious one. The 20 examples above keep that balance — most pair one practical line (rest, no rush) with one human one (we miss you at the table). Lift the pair you like.
Usually not in the card itself — the card is for warmth, not a status update. Mention you're thinking of them, that they're missed, that there's no hurry. Save practical questions for a follow-up text. The wishes above are written for that distinction: warm in the card, the logistical follow-up belongs to a different conversation.
Yes — that's the recommended way to use them. Most wishes here are written generically on purpose so you can replace one phrase with a specific name, date, place, or memory. Our AI generator will also rewrite a chosen wish around personal details you provide.
