Yellow spots

My face broke out with a rash earlier this week - yellow smiley spots. Sometimes, the spots were on my forehead, sometimes on my cheeks, then all over my face.
I guess I was contagious because all of a sudden, all the spots jumped over on mamma and continued to migrate all over her face. YYeeeewww!
Finally, we were both well again. The spots jumped over on the mirror and resided there for a while..... forming all kinds of different patterns.....
