my new friend

There is a little boy in my building who knocks on my door all. day. long. He's been yelling my name outside my door for the last hour.

It started at the end of last week. He's really adorable and friendly and precocious so it breaks my heart to not let him in, but I honestly can't have a child in my apartment when I'm working during the day. Between the chain smoking, the TV-14 rated shows being watched, the great deal of attention I need to pay to what I'm doing... all of these are reasons I can't have a child under five around me during the day.

I think he stays home with his dad/mom's boyfriend during the day, which is an awful lot like my situation growing up, so it's that much harder to turn him away... but you guys. It's constant. Not to mention it upsets Wagandstuff to hear someone dancing outside our door, so my options are this: invite a little boy into my apartment or have a chihuahua barking in my ear all day. I've tried to explain to him that I work from home, I've tried to tell him he can come and hang out with me after 7 PM, I've told him I feel really bad about not letting him hang out with me... but he just wants to chill.

I don't know what to do. I guess I could say something to his mom or the landlord, but I really don't feel like it's my place.
