The answer in the app was "They ate a while ago." Here, if someone asked when I sent an email, saying "just now" would mean keep refreshing, it's being routed. "A little while ago" would mean be patient, something may be wrong, but maybe not. And "a while ago" would mean that the email was sent so long ago that it probably needs to be sent again. There's a definite difference between the three (here anyway) in terms of time length. Can i sted be used for longer lengths of time? Because, to me, the answer seems to imply it. Thanks.
