Is he that non-observant?

So, the kids came home today. First, my daughter didn't do her homework.....grrrr. Second and most importantly, sn, who has respiratory issues was breathing very fast and wheezy. Could the ex not have noticed that and asked me to bring over his nebulizer? I gave him a breathing treatment, and his respirations are back to normal, and has just a little wheeze to him now. For crying out loud, we only live 5 minutes apart. I guess his girlfriend's daughter having her baby today was more important than his son's breathing.
