i.e. Those emails where you get a message that the sender has asked to be sent notification when you've opened the email. Does anyone else find them vaguely irritating? To me it feels like they're trying to check up on me, and/or looking for an excuse to be offended because they can tell I looked at their email hours ago but haven't got round to replying. So I always click the button saying "Don't send" and feel childishly satisfied that I've foiled them.
Yes, I know I could set it so that read receipts will never be sent, but I feel I want to know who the control freaks are. I know I'm BU and irrational, and it's a total First World problem, but there you are.
