I'm going to block a mentally disabled girl from contacting me
Why would you be so mean to this girl?
She's keeps trying to communicate with me, I just don't want her distracting me.
It's not nice to ignore someone just because of a condition she can't control. You should be more accepting of mental illnesses.
Who cares? I have better things to do with my life than to care about her.
It can be frustrating to be bothered when you are trying to concentrate but you shouldn't block them. Even if they are mentally disabled, you should consider asking her to contact you less.
