"Oh, thank you, Mother. Now I'll write the invitations."
"I'll help you," offered Flossie.
"I'm afraid, dear, you can't write quite well enough," said Nan with a smile. "But you may seal the envelopes for me, and put on the postage stamps."
"Oh, I like to do that!" cried Flossie. "The sticky stuff on the stamps tastes so nice on your tongue."
"It is better to wet the envelope flaps and the sticky side of the stamps with a damp cloth or a sponge than with your tongue," said Mother Bobbsey. "I'll show you the way."
So when Nan had written out the invitations on some cards, she and Flossie put them in envelopes. Then Mrs. Bobbsey gave them each a little sponge, which they dampened in water, and with that they moistened the sticky places, both of the stamps and the envelopes. And so the invitations were made ready to mail.
"Have you invited any boys to the party?" asked Bert.
"Yes, some," answered Nan. "But only a few."
"Then I'll come," he said. "I don't like a party with just nothing but girls."
"And I'll help Nan bake her cake," offered Flossie.
