To a certain member with whom I ended up being quite difficult toward.

[Sazabi]

I wanted to apologize for ending up on the wrong foot with you; I very frequently change my mind on things that interest me, and as a result, well, it can make me a bit scattershot and difficult.  Furthermore, I tend to write messages in a manner that, once I read what I'd written later, happen to be blunt and perhaps even rude; this is simply a manner of writing that I need to work on, and I am sorry for any bad feelings I've created between us.

[Edit:  The reason why I turned down some of the trade offers was because it seemed that you were really looking forward to keeping this or that item; I simply didn't wish to have you part with something that you really enjoyed.  That wouldn't have been right, in my book, seeing that I could tell you were quite happy having come across it in the first place. :/]
