"Did you always have all those little dots on your face?"

I started attending a spiritual group for a few weeks, and I quickly grew to love it. After the meeting, a bunch of us would go eat at this little restaurant and just have a good time.

An older gentleman, an amazing mad scientist, soon joined. I was totally fascinated by him and I was eager to talk to him one-on-one. 

One day at the restaurant, we ended up sitting next to each other and chatting. All of a sudden he said, "What is that on your face?" 

Confused, I asked him to clarify. 
He replied, "I didn't have my glasses before. Did you always have all those little dots on your face?" 

I was stunned, and I managed a quiet, "Yes." 

I never returned to the group after that. I was plagued with mortifying thoughts of how he could ask that in such a way, as if it wouldn't offend me. 

My skin is clear now, but this still sticks with me.
