How to handle noisy neighbor in the morning?

I am currently in a residential neighborhood that’s been pretty quiet. Recently, though, one of the neighbors (we’re back to back so I’m not completely sure where the noise is coming from) has either the TV or radio on in the mornings–think around 7-8:30 AM.

It sounds like a Mandarin news or talk show. The volume is LOUD: I can hear it through my closed window. I think this person has the window or doors open perhaps while getting ready for the day or to perhaps to hear over the noise of the household or cooking or something.

It’s really obnoxious, but I don’t want to go outside and start screaming at them to shut up. I was thinking of writing an anonymous letter, but I was wondering if anyone had any other suggestions.

How long would it take to learn Cantonese and Mandarin?

I am asian and I was raised in a cantonese-speaking household, but did not live in an asian country. My cantonese was learned by listening to my parents. I can speak cantonese but my vocabulary is very limited.

I want to learn to improve my cantonese to a wider vocabulary and I want to learn mandarin as well in case I visit an asian country, or meet one of my dad’s friends I don’t want to not know what to say.
