Hi guys
Thanks for the answers.

- Monday night I moved his clothes aside (they were dry), and put mine in that common place.

- Tuesday he wrote "Under which right do you move my clothes......., if this continues to happen, I will talk to the "gerance" (the one who take care of the house" ". With Signature and Name and address.

- Wednesday SOMEONE wrote "Ah, I see that your clothes are still there, do you think it is normal".

- Thursday (yesterday) I found this letter (when I remember that I've put my clothes 3 days in the Drying room). I am not sure whether SOMEONE is HIM, or another one (second one's writing style is 70% similar to the first one)

Then I tried to check the name and address, but didn't find out.

Further than this problem, I find the Laudrying room's rule is quite unreasonably strict: "Each family has only one fixed time in a week (2-4 hours) to do the laundry".

Cheers :-)
