Anonymous Mister MicawberDo you have a DICTIONARY? Can you find 'apon' in it? I think you will have difficulty doing so, because it is not an English word.Now, use your new dictionary to find the various meanings of 'upon'.I find your comment to be very rude. If you feel the need to answer a question you should do so without sarcasm and insult. There are plenty of places on the web for you to flex you cranial member, that you should not feel the need to be so pompous here. Upon reading your comment I find you answer to be completely useless.
I didn't find his comment to be rude in the least. In fact, if I were one to be offended at the slightest of provocations, it would be yours that appears in poor taste. Whereas he merely gives reference as a proof to back up the veracity of his claim, you take the opportunity to construct a personal attack based on your presumptuous interpretation of his intention. Congratulations, you've made quite the impression!
