Translation from German to English? Postcard dated 1918

[Friedland]

Hey guys,

I posted a picture of an Honour Cross w/swords and the accompanied photos and death card a few threads back. On the reverse of one of the photos is some writing (I'm guessing from a family friend or comrade of the aforementioned infantryman Jnatz Furlauf).

Just out of interest, I was wondering if anyone could translate the brief inscription? I've adjusted it slightly in photoshop to try and get a clearer image.

Thanks!

It says...:

"Lugau, d. [= den] 15.5.18.
Liebe Schwester u. [= und] Schwager!
Die besten Pfingstgrüße
sendet Euch
Adolf Thiede"

...meaning...:

"Lugau, 15 May 18
Dear sister and brother-in-law!
The best Whitsun greetings
to you from
Adolf Thiede"

(Lugau is a town in Saxony. Whitsun 1918 was on 19 May.)
