It doesn't usually bug me that much unless I've been misunderstood; otherwise I'm a fan of self correction.
Let me tell you a story about mistakes:
A few years ago I was going out with a beautiful girl by the name of Akane who I was really interested in. Things between us were going great but after a while I started thinking that something was up because everytime I asked her to call me, she would say OK, but she never did. I'd wait a week or two and then call her myself, asking for an explanation which she would never give. She'd just say "I thought you would call ME". I guess the penny should have dropped then, but it didn't. Instead I started to think that the girl was playing games, being nasty, or just weird. I should add that at that time I had only been in Japan for less than a year and my Japanese was quite poor, but still I insisted on speaking to her in Japanese exclusively (unless of course I was completely stuck; then we'd switch to English, at which she was actually fairly good). Anyway, this problem continued for a bit longer until we finally parted ways in a haze of confusion, misunderstanding and bad feelings.
A little while later (I can still remember the exact situation and instant that the penny finally did drop) I was speaking on the phone to a Japanese friend of mine in Japanese, and just before I was to jump on the train, I wanted to ask her to give me a call next week so I said 「来週電話する」 and promptly hung up. A few moments later I realized why Akane never called me, as the gravity of my monumental error hit me!
Needless to say I tried to get in touch with Akane after that to explain to her why I never called even though I kept saying I would (adamantly) but alas she never answered her phone when I rang. I felt like such a clutz that I tried to call her once or twice a week for about a year before I finally gave up.
It still pains me to think about it because I really did like her, and she must think that I'm a complete bastard who never kept his word too.
In any case, I'm extra careful these days to make sure that what I want to say is actually what I am saying, just so I don't commit another disastrous error like that again. :banghead:
