Unless you are the other parent, BUTT OUT. You won’t know what issues with finances, special needs, low SATs or grades, etc. could be complicating the college search process. Plus, knowing your kid is going to school in state and applying to UVA with JMU amd CNU as backups is very different from applying to T25s or SLACs. Other relatives, neighbors and friends don’t get a say, aren’t entitled to explanations or justifications, and shouldn’t have opened their mouths to being with. Your role is to say: that’s so exciting! When you are told where the child will attend.
If you are the other parent, get on the same page as your spouse, out of ear shot from your kid and present a united front. College applications are stressful enough without parents sniping.
Unless it’s your ex-spouse, in which case I suspect you have bigger issues then this. Sit down and agree on parameters for budget, cost, division of labor, checking, the role of each parent, etc. Then, remember this is very stressful for many kids, and you love your kid more than you hate your spouse and work together so your kid doesn’t hate you both and refuse to come home one she leaves.
