I have always tried to help anyone who asks questions on here, although with your obviously immensely superior expertise in the photographic world, your far more educated adroitness is boundless in its limits, so my puny attempts at imparting knowledge will never match your proficiency, so i will bow in deference to your erudition.
Personal abusive comments are usually the sign of poor education, low IQ, lack of respect and a basic difficulty in mastering a native tongue, reverting to "name-calling" as per a nursery school attendee, who quite frankly know no better. My son grew out of that at 7, as do most normal people.
Also, I happen to be able to spell Tweedledum and Tweedledee correctly, so for all my apparent faults, I am at the very least, not illiterate.
There are many words here with more than 4 letters, so a dictionary may come in useful for you, although I would suspect, your house does not harbour one.
