Awww... I'm jealous ╯︿╰ Kidding! 😁
In my 26 years of existence, I haven't received any postcard from anyone. Although those places can be searched all over the internet, still there is a giddy feeling when someone thought of you when they got there and shares it with you.
You are so young, maybe as technology took over this "old school" way of sending greetings you missed receiving a postcard. It can be also the thing that I am a bit older haha, so we indeed had just the postal services to send some cards, before the digital form of them appeared :)
Still, I do hope you would receive it at least once a postcard ;)
