What warnings and gifts are given to the children?

The three women tell the children that they have to leave them now and that they will no longer contact them. As they leave, they give them gifts: Calvin the gift of communicating with others, Meg the gift of her faults, and Charles Wallace the gift of his childhood. As a last gift, Mrs. Who gives Meg her spectacles and tells her to only use them as a last resort. They tell Charles Wallace that things will be especially dangerous for him, that they should never separate and that he should not think that he knows everything.
