I'd say , let it go . If anyone did do something , they'll know here that it was never received . Same for those who received and didn't know who they were from . As to the mail SS ... I thought it a little too pricey for some of us here ( that's why I didn't sign up ) ....Between spending $20 and the mailing some moms/dads may have said " no". Also, maybe the addresses were wrong and peeps didn't put return addresses on the package . I got a card that was addressed to 94th St instead of 49th St... but the zip was right .I was lucky to get it .
