I say she probably gets a lot of satisfaction out of the earning and "spending" of her money. I hope she involves herself with the church and they give her a voice to suggest what is done with HER money. That would keep her mind active, as well as her heart.
The other possibility is that some shady fucking "church" is manipulating her out of all her money. That is too depressing to even think about.
Is she Catholic? Maybe she wanted to be a priest and in her imagination the free samples are like the Eucharist wafer.
