Teenager,
You are right that you cannot expect 0 to 100 in one day but the people who are trying turn them “on” should not be the ones introducing co-ed etc. A silly example would be a student who is really misbehaved, so the teacher wants her to go from doing 10 pranks a day to doing only 5 and from talking non-stop to only talking every 10 minutes. Will the teacher plan pranks with her that are a bit more toned down then what she’s been doing until now? or will the teacher not help her with her pranks but turn a blind eye up to a certain point?
What I mean to say is that people might want to turn a blind eye to certain things that teenagers do and rather focus on worse things. However, we are not allowed to Encourage co-ed etc. That is the wrong way to go about it!
