Collin in particular, who always sounds mentally disabled when she speaks...or very very stoned.
I have a friend who suffered a stroke in her 30s and it was a very strong one that we thought she'd not recover her former life.
She has very much recovered but her speech sounds much as Collins only a bit more slurred.
In social occasions (my friend who does NOT imbibe)my friend has been thought by those who do not know her to be drunk and they have actually made fun of her - to her face!
