Whatever floats your boat!
You have to stay true to yourself
As for irritating someone... my only suggestion would be don't worry about it!
You're not intentionally trying to irritate anyone. When posting, just like in texting and emails, because you can't hear the inflection or tone in which it's being said, it's very easy to misinterpret how something is meant. If someone chooses to read more or less into something that's written on here, you can't do anything about that. If you really feel like someone took something wrong, you can always pm them or just make a general post, but I think everyone here understands things can come across "off" sometimes, so I really wouldn't worry about it.

Any suggestions?
