My youngest son, Conor, suffers from Asperger Syndrome, a condition on the so-called autistic spectrum. Typical of children with this disorder, Con has difficulty with social interaction (problematic, but not disabling) and an accompanying attention deficit disorder, much more an issue.
The latter is manifested most often as a difficulty in staying focused, taking responsibility for seeing things through to their necessary conclusion, and understanding the consequences involved with not doing so. The combination of these factors is wreaking havoc with his school performance, not helped by being in a new educational environment (middle school) this year.
If you have a chance, please pray for him to achieve a simple need - the necessity to appreciate the importance of turning in assignments which he's spent the time to do (most often very well-done), but for which he often goes uncredited because he can't/doesn't carry through to that final step.
