Whether or not other people seemingly can't focus because of public signs of affection doesn't make it their business.
Yes it does, and I'm not the only one that sees it this way. Lots of people don't want to see that ****. There is plenty of time for this after school, and people should have the consideration to wait until this time to display their affection. More importantly, it's going to happen no matter what the rule is, but the school's administration should undoubtedly prohibit PDA so that the occurrence of such instances will be minmized. Schools have goals, and activities that disturb the learning process makes it harder for these goals to be reached.
In an environment that attempts to simulate the environment experienced in the real world, is the school really teaching the students anything if something so trivial can throw them off for the rest of the day?
High School and most colleges do not simulate the environment experienced in the real world whatsoever, nor do many of them attempt to do so. However, school
should illustrate that there is a time for work (in this case, school time) and a time for leisure (in this case, after school), just like in the real world. Adults are prohibited from kissing or being clingy at work for good reason. PDA doesn't have to 'throw someone off for the rest of the day' to be a distraction, either. It just gives students more non-educational material to think about and gossip over.
What is to be said of the people in the real world, if such things can really facilitate such a fixation that it destroys the ability to focus?
Everyone is different. I'm sure there is something that would hinder your ability to focus in school, but let's say that you're just very special and can focus under any conditions. There are many people who cannot, and to me this is understandable.
It is perfectly understandable if the person in question is annoyed during the time of, but after?
Just because you see a couple kissing and are distracted enough to think about it later in the day or bring it up in conversation during school hours doesn't mean you are immature or that you have some kind of disorder. It's a distraction that makes learning more difficult for students (as a whole).
Naturally, there are and should be limitations as to what can be done in public and what can't, but still.
What limitations? Where would you draw the line, and
how? You must be able to put this on paper and it's meaning must be perfectly clear to anyone who reads it. If there is any gray area the rule fails.
If that one hug or kiss gets them through a badly started day, then how are they wrong? It's like a husband and wife who kiss before they begin their day. How is it wrong?
The husband and wife are kissing on their own time. Students can kiss all they want before school, and after school for that matter.
But regardless, who has the right to break up people who are happy together, even for the moment?
Teachers do. Students aren't in school to make out, and it is the teachers' duty to discourage any activities that obviously have nothing to do with education. If you let students have an inch, eventually they'll take a yard.
It's like drugs, you get high, then you feel like garbage. Withdrawal will hurt a lot. But if it isn't harming someone else, why stop it?
Sorry, but this example is terrible. Drugs often hurt the friends and families of individuals who abuse them. They are also known to do a number on an individual's ambition and intelligence, as well as hinder one's coordination and decision making abilities (which often leads to accidents and injury). Hopefully you aren't referring to getting high before or during school.
