I'm sorry Growlycat... I agree, feeling forgotten totally sucks, especially when the other person *offered* to do the check-in in the first place!

Not sure if it helps, but sometimes emails also just get lost. It sounds ridiculous, but it actually happens (I have no clue how). I had a friend send me an email about something, then immediately send a followup a few minutes later. I got the 2nd email, and the only reason I knew it was #2 was because he referred back to the first one, that never came to me!

Sometimes it helps to think about that when I reach out to someone, that they might have tried to contact me and it got lost in cyberspace... I hope you're able to reach out to him and let him know how you're doing!
