Why neighbor duck tapes my wind chimes?

I live in a duplex in the bay area. My next door neighbor has now tapes my wind chimes twice. Last night I posted a note at my door please do not tape my wind chimes.The last two renters never said anything about my wind chimes. I have been here 3 years now with no problems until now. I never complainted about the loud parties, all people coming and going all night.
