Just recently, a teenage guy with his hair dyed gold popped his
head over my sheets of plastic to get our attention, as he was
selling ice cream @ $10. I live in a corridor flat, and have
specially purchased those plastic slates to prevent people from
looking into my home. I was walking in my underwear back to my room
when this happened.
This young man did not even bother to apologize to myself or my
family members for invading our privacy, and continued walking
about in the vicinity to peddle his ice cream.
Not to mention, this was not the first time these imbeciles
messed about with the residents around the area. I have had
teenagers vandalising private property, swearing at residents for
not buying their low-quality and overpriced products, and the
like.
It is unbecoming of the younger generation, and it worries me to
wonder about their future. Sigh. 
Since you did not feel shy or cover up, he thot that was usual of
you, so no need to apologise. Selling ice cream boy, what you
expect??? and you cannot take that to compare with we young peoples
ya.
