trends we're seeing are very encouraging. if they continue, then there is the light at the end of the tunnel for a lot of children in schools. i'm a pediatrician. and it is critically important that we keep children in school learning. and as it is safe to do so, it is important that we're able to normalize the behavior that a child has. for a child learning to speak or learning to read, who speaks another language, not being able to see teachers face, that has real impact. but i think it is really important with each of these announcements and i wish i heard more of it, to say that this is being done because the numbers are moving in the right way. and if things turn around and we may be back to you saying we have to put masks back on children. these are things that could go in both directions an the more you let people know that. the easier it is if there is a new variant, if there is a reason why you would need to put this back in place that would you be able to do so.
