Premise: The Lea girls had known that the Forbes girls were going to give a party , but they had not expected that Patty would be invited .<br>Of course , Clare Forbes was in Patty 's class at school and was always very nice and friendly with her .<br>But then the Forbes set was not the Lea set .<br>Carry ran upstairs to Patty 's room .<br>`` Patty , you dropped this on the floor .<br>I could n't help seeing what it was .<br>Why did n't you tell me Clare had invited you ? ''<br>`` Because I knew I could n't go , and I thought you would feel badly over that .<br>Caddy , I wish you had n't seen it . ''
Hypothesis: Patty was asked why she did not tell about Clare's invitation.
