I wouldn’t have thought that a sarcasm tag was necessary, as it seemed obvious. Since you missed it, to clarify: that was 100% sarcasm.
Sarcasm tags seem to ALWAYS be needed and that is the reason for my sarcastic tag line.
“I’m all out of sarc tags.”
In fairness to others I note that sometimes sarcasm in writing is not so easily detected as it is during conversation. Voice inflection and facial expression do not appear in writing.
