Calling me out on a clarification when you're banging on with ad hominem rubbish?
Respond to the point or bugger off. I'm not here to impress you, you're not my dad.
Third, that sloppiness and failure to pay attention is only reinforcing my initial impression.
A good engineer knows when the details matter and when it's just wasting everyone's time. Would you classify responding to someone being needlessly hostile as something other than a waste of time?
If anything you should be criticising me for choosing to spaff more time on this conversation.
