I don't know could I just leave my family and friends, they wouldn't want me to go. Then again I don't know could I decline an opportunity like this...
Going there would mean that I wouldn't have to worry about the future, but since I don't really worry about it anyways, it wouldn't really affect the decision. If I had time to tell everyone, then definitely, but the rules won't allow that .
Whatever I would choose, I would probably be sad for a while after. It feels sad to say this, but I guess I would take the portal: with ponies cheering me up, I wouldn't be as sad as when declining a life in Equestria. I would hate myself for leaving like that and leaving everything behind, but I guess I would get over it with time.
