Was steht da?

My dears!

Accept my heartfelt greetings.

*still can’t figure the third line, likely stating the current location of the writer*

I haven’t received the package yet

it takes about 14 day to arrive

I will write you when it arrives

I’m healthy and I hope you are too.

Kissing hand *a name, ending with -ouš, meaning it’s most likely a domestic form of the name*

Drazí!
Přijměte srdečný pozdrav,
?zdreha? / ?Zdrehci? vzpomínkou
ten balíček jsem ještě nedostal,
ono to trvá asi 14 dní než
to přijde, já budu ještě psát
jak to došlo sem. Zdráv a
doufá, že vy taky.

Ručičku líbám, ?R?mouš.

You can have the czech translated into english with AI or DeepL or something, couldnt be bothered

The letter countains bad grammer, odd spelling and words I can’t read well. I’d guess the writer was from eastern Moravia, perhaps? This would probably be tanscription.
