history: I get very annoyed when people don't return or acknowledge emails.  I find it odd -- and annoying -- when people don't respond to or even acknowledge emails.
current: Well, sometimes people are busy and don't have the time to check emails
next: It would be great if there was a way we could all tell the best way to reach someone -- I know some people prefer texts to emails -- but if you're in a work situation, how do you ensure communication?
