Definitely both, pick your topics and don't come over as a bit mad and you should be OK.
I've read your other OP and you may have perfectly good reasons to be cross but the way you've written it is likely to put peoples backs up.
Can you really not see that suggesting that people don't like you because your child is too good looking is just daft and of course people are going to pick up on that, its just humna nature.
If you give off combative vibes then you will get them back.
I hope you can make some friends at your school but I wonder if you aren't going about it in the bast way.
