But lately he seems to _______that the benefits of forming complete sentences when communicating are________of the effort.

Butterflies. Of course. I rushed to_______them from the garbage,_______them off and handed them to my young artist. “Want to see them________again?” he asked with a shy smile. “Oh yes! They’re beautiful.” I whispered. He ran back upstairs to float his _____ down again. They really did look like beautiful butterflies.
