Оригинальный текст - Голландский - Beste suders heeft op de maan-dag ag en urydag...

Could you make me a bridge into English, please? Thanks.

It's not good Dutch.. probably written by someone who's learning.. I can make sense of some things, but I have no clue what is meant by 'suders':

Dear 'suders'
has on mondays and 'urydag/ Fridays??' physical education and has to bring:
1. a pair of shorts
2. a t-shirt
3. a towel
4. clean underwear

Greetings
your teacher

Suders has to be "ouders"

Maybe it was written by hand so the "O" looked like an "S"?

Dan veronderstel ik dat urydag, vrijdag is?
Zal het gelijk proberen te vertalen.

Dear parents
(there's no reference to a name, but it should be here) has on Mondays and Fridays physical education and has to bring:
1. a pair of shorts
2. a t-shirt
3. a towel
4. clean underwear
