Either you've hit some hot topic in my personal history, and I'm ranting because I'm temporarily blind to my sense of proportion.
Or what you said really isn't small and inconsequential, and my rant really isn't disproportionate.
Just occasionally, it's both. Then you'll see just what a real rant is like. It happened today.
Apologies. Not for the message, but for the delivery. It really is nothing I can help, you understand.
