sometimes you should apologize
I have been thinking about this post a bit. The basic idea is that if you feel the need to apologize for an email you send, phone call you make or blog post you write that you should just not call/send/write.
Generally i think this is true. But, I think that if a mistake on my part made the sending necessary it is OK to apologize. For example I recently sent an email to 10 or so people I work with. I needed to send it, it was relevant, etc. However, after I sent it I noticed that I had done something crazy to the formatting and it was basically unreadable. So, I fixed the formatting, added a “sorry to send twice, here is why, here it is again” note at the top and sent it.
I think that it was good to acknowledge my mistake and the annoyance I was going to cause.
