Now you have really "schooled" another in a way that being sarcastic and condescending does not.
The former educates, the latter breeds contempt.
I have been guilty of it from time to time while for others it is modus operandi.
You could have described the process with more detail.
You left out any information on the purpose of using the lock system, why it is necessary.
Keep at it, you will get the hang of educating others.
It takes practice, patience, understanding, and the awareness that individuals will accept and apply their new found knowledge differently.
I think many on here may be either taking differences of opinion very personally or taking their everyday life frustrations out on others.
Sure, everybody feels good when others point at them and say, "now there is someone that I agree with", but is that, rather should that be the goal of conversation?
I'm not against heated, impassioned debate, it is taking jabs at others solely to be mocking that I oppose.
