I did that in an email the other night, then woke up long enough to see it and start deleting it, but nodding back off hit "enter" instead leaving a huge gap between the ajfhusitiiiiiiiiiiiiiiiiiiiiiiii and the apology the nex morning.
Funny thing on my end I saw it all in my sent box, but the other person says they didn't see any of it
(or... they were just being nice)
