HappySurfer is Disgusted Sometimes
You have a fairly thick skin. Something has to be truly revolting before it grosses you out.
You probably weren't always this way, but you've learned how to toughen up. Good for you!
It's fine to be disgusted by totally disgusting stuff. And you know better than to gross anyone out yourself.
Given enough time, you can get used to the most nauseating of situations. You can develop an iron stomach.
