I suggest reading this to understand why some people will seem mean to you online when the reason isn't obvious to you:
Looking at your VMs with him, you seem to have done something to annoy him. A lot of people don't like being bombarded with 3 messages proclaiming the same thing in a very short time, and some people don't like it when people don't use proper grammar. And then there's the whole repeating letters thing you frequently do -- many people don't like that either. Doing all 3 of these things will cause some people to essentially make their words drip with venom because those 3 things so very much annoy and irritate some people. It's something that comes with typing like you do. Since I think you've got the potential to be an upstanding citizen, I've got some tips for you that will help you 1) appear more mature, 2) not have as many people being mean to you, 3) get your ideas across better to others without annoying them, and 4) help you do better in school by giving you practice with your grammar, spelling, punctuation, and patience:
First thing you need to do is to use proper capitalization. This means capitalizing the first letter of the first word in a sentence, as well as properly capitalizing place names and the name's of people. Second thing you need to do is use proper punctuation, meaning ending all of your sentences with the proper punctuation mark, as well as using commas at the appropriate places in a sentence. The third thing you need to do is to not repeat letters in the way you did when you asked me "and also wazzzzzzzzzzzzz uuuuuppppp". Quite a large number of people do find that oh-so-very annoying. Fourth thing is to try to avoid repeatedly sending people the same messages.
And one more thing: Always read the rules and make sure to follow them! Ask questions of the moderators by visitor messages or by private messages if you have questions on the rules!
Hope this helps!
