I'f I should take take care of my favorite pony. (since I like luna, derpy, flutter and vinyl as much i have a prob)
It would depend on the situation.
I would be surprised.
If like I take care of my sister I would just treat them nice and help them if they needed something. (if vinyl i had given her a pc.)
I would probably be very careful if it had been injured and do what is possible to help.
(if wounded it had been removing bullet/knife/nail/whatever it is, giving painkillers, cleaning and bandage.)
I would do it whatever my family says. (IT IS A PONY COME ON)
I would as of a brohoof, nothing more.
