I mailed difficult child a card with 10 3x5 photos in it last Tues. morning. He never received them and I assumed the photos didn't pass Department of Juvenile Justice's screening. But I just got the unopened envelope back with a sticker that says "returned for "17" postage". Does that mean I owe 17cents in postage? I didn't think it weighed much. I can't believe it took the post office a week to put that sticker on and return it- I mailed this directly at the post office that delivers mail to my house. And- I use the Forever stamps- aren't they supposed to cover any increase in postage costs?
