yesterday finally met a friend after a long time. and he got me this funny burglar alarm which he found in his aunt’s appartment. i always loved these old things. he said it doesn’t work, but i tried it at home. first the light worked, then my brother found the secret to this wonder machine. if you pull out the black string, an enbearable noise starts. no doubt it keeps all the burglars away. or else, gives them a stroke. nearly gave me one, for sure.
