Covering for a Lack

Lyn's bowling scores last week were 173, 81 & 80.

She brought home a copy of the score sheet "since it's just easier" than to remember.  Mom said "She always seems to figure out a way around something, doesn't she?"  Lyn's been bowling forever and she's never brought her score sheet before.  I have to hand it too her that she's still using some problem solving skills.
