i feel bad for those of you who think it's embarrassing or helicopter-like for someone to bring a parent to tour the law school. are you kidding? clearly, your parents have never shown an interest in anything you've ever done, and it shows. lol. if parents are paying for travel costs + part of tuition (in some cases, all), then don't worry about it. that student is already 10 steps ahead of you, "breh"
What you're missing is that bringing your parents to school will incite two separate and negative emotions: superiority and jealousy.
Superiority is from the fact that most normal adults can take care of our shit, and don't rely on our parents to bail us out of the end-of-the-month blues. We're our own people, and we make our own decisions. We assume that our coworkers do the same. That independence is highly treasured. Most of us have had some hard times, and we're proud of our ability to get through them.
By jarring us out of that by introducing your parents, we will feel innately superior to you. Simply put, we have dealt with shit that you have not had to deal with. It will exclude you (at least partially) from the grownup club. Grownups are expected to be responsible, timely and professional. In a profession where your reputation is important, this is a big deal. Get a reputation as a daddy's boy/little princess, and people will NOT like you, especially when you screw up. They will blame your entitled nature.
Second, it inspires jealousy. Yeah, you're right, you are extremely
lucky to have someone pay for your law school. Really, I'm not joking. It's fucking awesome, and a huge gift. I'd love to have my parents do that for me.
But most people (myself included) would be jealous of this. You have access to a whole series of resources that they do not, and will never get access to. That is a divide between you and them. And, believe me, a smug attitude does not help your case at all.
People think that lording it over someone is the sign of an immature child who thinks they're superior just because he got lucky in the gene lottery. Most people want to be lucky at the gene lottery, and holding up the winning lottery ticket to them and laughing will not engender feelings of good will.
Righteous or not, most human beings will feel jealousy in this situation. They might bottle it up and smile at you, or decide that you "didn't mean it that way", but in their hearts, they know that you are a lucky bastard who is luckier than they are. And quite a few will dislike you for it. Sorry, it's human nature.
To recap: don't bring your parents if you can help it. You will be dealing with a lot of people who did not grow up as lucky as you, and they will NOT like you for drawing attention to that difference. If anything, you will be telling them that you are an entitled prick.
