What does Lily Dale do every time she feels blue from missing her son?

Will gives Lily Dale $5,000 for Christmas every year. He has done for the fifteen years prior to the action of THE YOUNG MAN FROM ATLANTA. On the one hand it is money that Pete earned, so he feels protective of it. On the other hand he gave it to Lily Dale to do with as she pleases, so it technically no longer belongs to him.
