This morning as I was leaving for work, Dominic told me ByeBye, which is normal, but then he let loose this gobbledegook with 'ood day at the end. It really sounded like he was trying to tell me to have a good day. Then as he and Rod were going to the gym at lunch, Rod sneezed and Dominic independently said bwess you, which he USED to say all the time.
Small steps. Good steps.
