This has happened several times in the last few months. I do a custom art piece, putting in loads of time and work. I put in more time framing it, make it look great. I tell the client I'm shipping it. I ship it. And I NEVER hear a word from the client. I check delivery confirmation so I know it's arrived, and I'd have to assume I would have heard from the client if it didn't. But I also have to assume one of several things:
1) they did email me to say it got there and I just never received it. I really do have a problem with not receiving emails sometimes
2) they just forgot to let me know, simple oversight
3) it didn't arrive. It was delivered somewhere else by accident, and the client has been abducted by aliens and never contacted me.
4) they hate it and don't want to tell me
If I ask about it, particularly after this long, it feels like I'm fishing for compliments. I'm not. I just want to know it got there in one piece and if someone IS unhappy I want to fix that! Seriously people, if someone sends you something they really care about, have the courtesy to let that person know it got there!
