This is so sweet and nice. I don't know why this sort of things (postcards, letters, etc) have more of a sentimental meaning than a simple text message. It might be outdated and old-fashioned, but maybe is that nostalgia that you mentioned that make us feel more emotional.
It's like receiving something from the past although it is in the very present.
It's nice that you got that lovely gift. Thanks for sharing this
Yes, they have more weight, right? And also the letters we were writing and receiving in the past... there were of different types hahahaha 💌
