You spend the day with your favorite pony, what do you two do?

[J.R. 3,183]

   If it was me and AJ, I'd help her buck apples and try all of her apple foods.

   If it was me and RD I'd challenge her to a friendly competition of speed and strength and/or pranking.

 If it was me and Rarity, I'd help her look for jewels and help design clothes for stallions.

[CC_Maud_Pie 6,431]

Let me use it in a way that it's my OC (pony version of me) and them:

 

CC and Maud Pie: Just walk around and look at rocks.

 

CC and Fluttershy: Walk around a good quiet outdoor area and have a long talk about our struggles.

[Petrus 696]

I'd ditch Ohio and go to pony ville to spend the day with everyone and help people if  needed

[cdx561 238]

Rainbow Dash and I would do lots of cool things like hang and pull pranks and also would also like to hang with

Twilight sparkle and do some reading

[Scream Lucid Dream 103]

I'd help AJ and Big Mac with their farm work, of course. It is convenient that my two favourite cannon ponies are bro and sis, and that they live and work together. And I would play fetch with Applejack and Winona. I loves me some cute dogs.

 

Derpy and Screwball I do not regard as cannon, but I would frolic and play with them (but I would probably need wings in order to accomplish this.) Just act all random and derp derp derp etc.

 

I might play Baseball with Screwball (yeah, counting the ways that could go wrong...)

 

And did I mention the derping?

[Fractured_Spectrum 201]

Rainbow Dash:  I would tease her, cuddle her, kiss her cheeks and make her my bestest friend ever.

Scootaloo/Sweetie Belle/Apple Bloom: Would cuddle, kiss their cheeks, play with them all day and make them my bestest friends ever.

 

The pattern is fairly predictable from here on out so I'm gonna stop. XD

Derpy or Rainbow Dash: I guess I'll just walk around and talk with her...

[Ashen Pathfinder 16,162]

Take nice walks under the wonderful moon, maybe study old literature, and talk about dreams.

[Odyssey 5,718]

I would probably just talk with Dashie about her interests and her ambitions. I'd also might like to see her perform some flying tricks she is practicing on.

[Admiral Regulus 2,769]

I'd be nerding out with Twi.

[baltosaa 86]

No idea.

 

Maybe talking about what flying is like with RD?

 

I have no idea what conversation I could have with Fluttershy,

 

I would probably have more stuff to do (Or talk about) with Twilight, really.

 

(I have no idea what would happen with Screwball. xD  )

[Rainboom Dash 1,056]

I guess we could do what she likes and also do what I like...

[Confucius 194]

I could talk about animals with fluttershy and take her too the forest for her to work her animal Magic.

With rarity I would try to get a personal hairstyle with her help.

Applejack would be fun to work with and vinyl and I could share and make music.

And derpy could help me forget me sadness

All these with a bunch of kisses and hugs

[Handsome Changeling 1,851]

Well with Pinkie, I would hope to pull some pranks and mess around heheh, then have a baking contest, I would likely lose but still, fun is fun right.

Now with Chrysalis I have no idea, maybe propose to be converted and join her legion of the swarm? Yeah that sounds pretty good heheh
