My trainees - PC? NOOOOO

I am delivering some training for a group of young professionals who need to learn how to communicate appropriately in the work place.

My group is great! They are lively, fun and interesting. And no politicaly correct at all.

The other day I was helping them with comparatives and superlatives. One of the guys stood up and said:

- Sarah is the fattest in our group.

I replied - Hassan, what have we discussed about hurting other people's feelings?

- Oh, miss, I am sorry. I forgot!!  Sarah is the heaviest in our group...

Sometimes I just feel like giving up all together...
