Not a good part of it, but it can cause a lisp.
I understand. but I know people with speech impediments and they do not have LAZY speech.
My wider point is that this girl is disingenuous.
She is making excuses for herself, and beyond that, she is not helping her cause.
She is articulate enough that she is showing how seething she is toward the ‘anyone but black’ community.
She just said “THere are a lot of BirTHdays up in THere, DeaF? I don’t do deaF”
This is not a speech impediment.
