Register a postcard Postcrossing

After a card arrives, the postcrosser registers the card.
When registering, we normally write something to appreciate it.

Sometimes nothing, in the case I feel very cold.
Maybe the postcrosser is the beginner.
Or the postcrosser hates the card.  I feel terrible.

Because I try to choose the right card for every postcrossers carefully as I bought many kinds of cards for Postcrossing. But sometimes their favorite cards are so limited so I can not find any suitable card, such as Medicine, Psychology, Space...etc.

Mostly they are pleased to receive the cards.
Some postcrossers received my cards.
They wrote.

"Hello name, Thank you for the lovely postcard.The stamps are very nice too. I wish you all the best, name"

Hello name,

I am glad that they liked my cards.
