Alternatives for "Sorry for my delay"

I feel like a weight has been lifted after reading What if we just stopped being so available? (The Atlantic, possible paywall). Joe Pinsker rants about the expectations of prompt responses and how we should all stop apologizing for failing to meet them. He says, “For one thing, having multiple obligations and priorities means that we are, all of us, in a perpetual state of delay on something, and apologizing for that fact feels like having to apologize for your standard mode of being.” He spoke with communication experts who suggest alternatives for “Sorry for my delay,” like “Thank you for your patience” or “I wanted to make sure I thought carefully about your good questions.” But I agree with Pinsker who prefers to omit an apology or expectation altogether and instead just write your message as if you’re responding right away, because content is more important than speed. This article is a much needed absolution. We all have the right to disconnect. — CD
