Sure, why not?

Okay, if she wants to throw you a party and wants help with baking, who are you to argue? You can do that. You stop by the local market to grab some supplies, then head over to the bakery. On the way, you notice a white flower sticking up in the grass and pick it. You arrive at Sugarcube Corner and are greeted by the ever energetic Pinkie Pie.

"Well did you bring stuff to bake?" she asks, trying to peek into your basket. She notices the flower that you've laid on top. "Huh I don't think I asked you to bring a flower? Who would ever put flowers on a cake, silly!"

You pick up the flower with your mouth, and lean forward, placing it on Pinkie's head.

"I thought this would look nice on you," you say while flashing your signature smile. Pinkie Pie looks as if she is becoming overwhelmed with emotion at your simple gesture.

"You're so nice, and we're going to be the bestest friends forever," Pinkie exclaims then takes the honey and dashes off.

'This is really easy,' you think, vaguely wondering if there is something you could do to up the ante and make it more rewarding. Just then a mare walks in and asks what Pinkie is so excited about.
