When Iris' fourth birthday approached, her mom considered all the usual tot-appropriate options for a party theme — "Frozen," "Star Wars" and Hello Kitty. But when Sarah Fortune Gill actually asked her little girl what she wanted, Iris' answer wasn't so usual: CVS.

Actually, it didn't come as a surprise to Gill, who was already well aware of her daughter's obsession with the pharmacy chain.

In a post on her blog, Gill explained that Iris' passion for CVS started when construction on the first one in their Arkansas hometown began two years ago.

"The site happens to be directly on our path to Iris’ school, so we drive past the location at least twice a day," mom wrote. "Being that she was only three when it opened, she watched the progress of the structure being built for nearly half of her life, so naturally it was a big deal when the store finally opened."

So when Iris said she wanted a CVS birthday bash, that's just what she got.

"When your kid puts CVS on the same level as [Disney World], you embrace it," Gill added. "When they ask for a CVS birthday party, you throw it."

Gill crafted CVS-themed favors for kids and adult guests alike, and she let CVS headquarters in on the plan.

The chain provided the family with even more favors, snacks and various party supplies.

And the location that so enchanted the little girl made sure to give her a special greeting on her big day.

Lest anyone think this is just some sly advertising the corporation arranged rather than really what a 4-year-old wanted, Gill offered this glimpse at Iris' CVS fixation 10 months ago.

There's no doubt about it: That's true love — for a pharmacy.
