you need a direct questions or statement to answer/discuss in your PIP.
eg. SMS bullying is it really that harmful?
and then you research whether people just delete these numbers or get a new number themselves. therefore avoiding it and not really harming anyone.
or does it really affect someone. what are the repercussions.
i did bullying for my PIP (2008). i found the more i reserched it I found points of it I was interested in. so i focused on that. I preferred to find out the repercussions of bullying rather why or how. i ended up doing it on 'does bullying lead to high school shootings?' a very scary topic but i found it interesting.
the key to a good pip is starting early and conducting a lot of research but most importantly being extremely interested in the topic.
