I theorize that this is the leading cause of "gap" between generations. Adults who are emotionally inept always say "it doesn't hurt that bad," "heartbreaks heal," "you'll get over this issue you are facing," "you'll forget all about this," or something similar. Those kids are going through something that they haven't ever experienced, and that hurts or is scary.
Adults have the experience to understand that things can change, but frequently lack the wisdom to empathize with the "new" factor for the kid.
