how about these topics:
1-why can’t some adults remember what it’s like to be a teenager?
2-is it true that there are a disproportionate amount of girls in shidduchim vs. guys? (have to have at least one shidduch oriented)
3-how can people overcome emotional attachments to gashmius
4-what are we/can we personally do for the yid/yidden that we know, that are not yet frum? (a personal favorite of mine)
I do have more but will start with this for now.
