I CAN'T BELIEVE IT

OK, my daughters birthday was Janaury 25 and being the good mother that I am, I sent her 2 birthday cards and a padded envelope. Only one of the cards had a check in it and in the padded envelope I had birthday candles - spelling her name and skinny post it notes (she loved post its). I mailed them 4 days before her birthday even though I was seeing her the day after her birthday I thought if something happened and I didn't go up. Well they didn't get there. THEY NEVER ARRIVED. Of course, I blame the post office - who else. I mailed them in time.
So, this past week I decide to send her something for Valentines and send it to her work address, not going to chance sending it to her aparment again. And being the lazy person I am, I have labels for everyone and I was getting a label for the card I got my Dad and I notice that on Sarah's address label it says aparment 6C. OH NO, I think, her apartment number is 2C. That explains alot but they haven't been returned to me yet. So, I tell her to go upstairs to 6C and put a note on the door saying that your Mom had a brain cramp and put the wrong apartment number on ALL 3 ENVELOPES. She does that and finds out that yes, they got them. They had moved in on February 1, and they were in the mail box. Now instead of writing 'return to sender' on the envelopes and dropping them in the mail box, they THREW THEM AWAY!!!!!!! I can't believe they were that - ok I'll say it - STUPID ~ RUDE ~ UNTHNKING. I don't know what. They weren't junk mail. Now, 2 had labels on them but hey, they were hallmark cards - you could tell they were cards. And the padded envelope was HAND ADDRESSED. And all 3 had the SAME return address label on them. And they THREW THEM AWAY!! I don't understand people.
