Crakkkers in Klass

I have to go to class on a regular basis. I've been doing this for many years already.

A couple of days ago I was in class again. The class was dismissed for lunch.

After lunch we were all in the classroom.

I'm not sure what happened but a few of the class members returned and began to crakkk Mexican jokes. They then began to crakkk black jokes.

I knew that they were trying to get to me so I ignored them. Exactly why they included black jokes is beyond me.  Were they trying to get to me with black jokes?

I'm not black. I'm immune to them.

I'm immune to crakkkers too.
