Hi guys! I work in an office, and I have a co-workers who are very obnoxious and they are the type of person who always makes fun of what I say specially when I ask questions, like yesterday our supervisor was not in her desk yet, then I ask my co-worker if she did not arrived yet, then one of my office mate said "does she looks like she's here" and then mockingly laugh. They are always like that, I just felt like they insist that I'm stupid and slow in comprehension. Any suggestion what will I say to them that will defense myself without looking annoyed. Thanks!
