3) No. A pre-birth foal has no conscious understanding of reality. If you have no understanding of the world in which you exist, you can’t cast.
The only danger would be if the unborn unicorn’s horn broke within the womb, and an injury severe enough for that to take place would likely result in a stillborn. Either way, the horn would sooner puncture through the mother than break off.
4) I’d not worry about it. In the grandest scheme of things, it doesn’t really matter. If you find somepony you like and they like you back, give it a shot. If not, they can still be your friend.
I understand it’s not quite that easy for human society, but it should operate on the same principles I would think.
5) I know, it makes sense in theory! And yet here I am giving a condescending reply. World’s funny like that.
Edit: That’s all the questions I have. If I haven’t answered one that you sent, I didn’t get it. I know a lot of questions haven’t been getting through to me lately. Feel free to try again!
