I spent an hour writing out all the invitations to my daughter's classmates.She told me who said they were coming.We spent so much time and money making gifts.“Tina would love the sunglasses，and Mike would love this pencil…” Jenny said.She helped me make cupcakes，60 of them with different colors and tastes.
Everything was ready.At four，it started to rain.And it didn't seem to stop soon.“Will they come at five？” Jenny asked me.She looked worried.I was not sure，either.We sat on the sofa and waited.At 4：50，Lisa，Jenny's best friend arrived.We were both happy and welcomed her.Until 5：20，seven of thirty classmates came.
I thought Jenny would be sad.“I'm happy today，Mom，” Jenny told me after the party was over.“It was rainy, but some of my classmates still came.I know who are my real friends.”
“Yes，it's the most important thing，” I said.
