Sometimes issues arise that you can't make sense of.
You really don't know why the issue is taking the path that it is.
It could be an issue of parent choice, student behavior, learning challenge, enrichment or more, and even with research, you simply don't understand what's happening and why.
After good effort and with as much respect as you can find, you sometimes have to lay an issue to rest hoping that someone elsewhere will have the better answer. In these situations, as long as there is not dire consequences or events, it's okay to simply say, "I don't know what to do, but I'll be as loving and caring as I can in the meantime."
None of us know it all or have all the answers. There will be times when we are stuck without the information or inspiration we need to make change or respond to situations. In these cases it's better to admit ignorance after you've exhausted all avenues, and let the issue continue as a point of reflection hoping the answer will come or someone who knows more will be there to take it to the next place.
