@Taylor Comer I second the advice about Google voice - free and super useful - you can forward it to your cell, have it be just on answering machine, customize greetings, etc. when the number gets called both my phone and my wife's phone ring and when a message is left I get a text and an email transcript.

I thought about getting headphones but if they cancel out sound, they may prevent me from hearing a sound that I need to hear in the middle of the night or in an emergency like my bell, a smoke alarm or my cell phone etc.

You can also Google that supervisor number they gave you, to see if it's just some guy's cell phone.

What about all the poor Chinese miners that are being poisoned half a world away mining raw materials for solar cell production?

They will talk loudly on their cell phones outside at 2am.  

absent some other explanation.always do put BY APPOINTMENT ONLY in my online ads but now more than ever, folks will show up at the door, knocking and everything, some even help themselves to- after knocking -walk into the driveway and around the whole premises 'inspecting' the whole building even if its just one unit within.totally understand scoping out a neighborhood, street, building, and yard before making an appointment but find ppl who just totally ignore whats written in the listing and instead will show up and rather know than call from their cell, inexcusable. maybe a decade or two ago when ppl hardly ever had car phones let alone cell phones it would be understandable but just dont get how applicants expect to be taken seriously while totally being blind to such simple 3 words.then on the flipside, there is the parallel to the story - where the person who calls an employer and/or walks in without appointment despite the ad clearly stating resumes only no calls no walk in applications available, etc - gets the job.

Ask your cell phone provider....

I am trying to evict him because I don't want bad thing happen like fall from stairs or even he die at property (because he got cancer)My questions are:Is the eviction right thing to do?

We only manage 2 ourselves, and when we're out of the country or on vacation where cell phones don't work well, we ask a family member to take the calls and give the tenants their number.  

A bad one is like a cancer you have to get rid of.
