At the beginning, before it became overwhelming and thus ignored, when it was from a top school one twin would ask if the other got the same mailing. If so, he wasn’t interested. LOL. I threw all college mailings most unopened in a file storage box just in case they ever wanted to look at them again before applying/accepting. After college choice was settled I took the overflowing boxes to recycling and mourned the trees. For 3 kids it filled more than 4 boxes.
