Better now than later.

It wouldn't be less intrusive if it was something non-sexual. Might as well learn something from a person she'd never see again.

With this reasoning in mind, Rose goes to alter the slice of Truth. She focuses on it and forms the sentence in a new one in front of her inner eye.
As she focuses in on it, she realizes that she's got no idea what to change.
Because she's taking a moment to think, Rose realizes that time has almost slowed around her. It's not that time has actually slowed, Rose just feels her entire being focus on this one aspect. Everything around her seems blurry, or unimportant. Her sole focus is this sentence, this true fact about someone else's life.
Time hasn't slowed down, but Rose does feel her own mind racing a mile a minute.

She looks at the slice of Truth again:
"Adelaine Summers started to heavily explore her sexuality with more and more **** kinks after her conservative husband's ****."
If it has to be a test, she could at least try to make it something this woman'd enjoy.
With that thought in mind, Rose changes the Truth. It's a simple as blinking once for Rose, but after she's done, she sighs as if she'd been holding her breath for minutes and she feels her heart racing as if she'd just climbed a long set of stairs. Using these powers seems to be similar to doing light physical activity. Nothing major, but it was good to know that using the powers required some actual energy.

She looked at the woman, nodding politely as they walk around each other. The moment of two strangers having met on the streets seemingly over.
Above the woman's head, Rose now can read what she'd changed:
"Adelaine Summers has found sexual fulfillment in following through with more and more **** kinks after her conservative husband's ****."

The woman breaks eye contact and begins walking away. Rose looks after her for a second longer. The gate of the woman is different, a bit strained almost.

Rose grins, happy to share this secret with this woman knowing she'd at least be happy. Rose almost didn't notice, but the woman's make up has changed too, being applied much more heavily now than before she the change. She was also unsure if the choker around the woman's neck was there before.

"Well, whatever the difference is, it's good to know that the changes are immediate and seemingly at elast somewhat retroactive? It's weird, but then again, everything about this is." Rose picks up the pace slightly as she forms these thoughts in her head. "If only I could find this man that did this to me. Why did he flee? Why did he do it in the first place?"

Shaking her head, Rose looks up again, feeling a bit aimless.
"Maybe just one more test to be sure?"

She lets her gaze wash across the many different faces of the people around her. Most of them look tired, focusing on their phones or on the ground in front of them. It's a monday morning after all. Rose almost spins around herself as she lets her eyes wander. None of the people around her lock eyes with her and at the end of her twirl, she stops as she catches her own reflection in the window of a store.

"Wait. Could I see my own Truth?" she whispers to herself and steps closer to the window.

Her reflection now coming into view more clearly in the dark window, she focuses on her own eyes.
She can't help but notice that one strand of hair that had come loose again, but it quickly becomes unimportant as Rose watches a bold red script appear in the reflection above her head.

The text isn't mirrored despite appearing as a reflection and it seems easier to focus on than the previous few times she's done it to other people.
