Thank you.. I do 100% agree that there's nothing wrong with 3.0, I honestly do, and FWIW have never bothered them about the grades or said that they are not good. I was around average back in my day and have told them that.
My worry is primarily about the insane amount of gaming that we're able to observe during summer and no idea if that was the case during the semester or if it will resolve during the fall when classes hit. It is definitely likely that there's some other underlying issue, but having a 19 year old share that with you is a hard problem, and hence I was looking for advise/pointers or general thoughts on whether I should just leave them alone and hope it resolves.
Unfortunately, to leave them on their own devise is not easy for a parent, but perhaps we should.
Sir or madam, you need to go see a psychologist. You have real control issues. You and your SO need counseling really bad. Go talk to a professional, I can't believe you are asking this question in HN! Funnily enough, even people here are more considerate than yourself with your sibling.
Your "child"(actually, an adult) is a person and a person has desires. They might be full of your shit and don't care so much about your precious investments you've made to get them the education you are paying for. They've never had to work for it. Does it hurt? You have to deal with this.
You are probably rich as you can afford this, so it means you are well-studied, so I'll suppose you understand how the brain works given different stimuli and you gave your "child" (of 19) the wrong idea about the world for 19 years, now you expect it to just get a wide comprehension of the world and perform well?
They will never be able to give as much value as for example, I would if I had that opportunity at that age, but I understand him/her.
You have a sickening desire of control of your sibling as if they were your property. You need to go see a professional, now.
You have no control over them, I bet if you keep being a PITA they will start doing drug and that will be all your fault. Get professional help before it's too late.
