Lost

Not everyone can reach either of those places. Some get lost. But you get lost on the way to someday, so you're hurt and lost both.

There are people who help you when you're lost. It's very easy to forget your someday and choose another to chase after that special person guiding you out.
It's easy to forget their intentions were just to guide you out. Not for you to trouble them along the way.

If you do change your someday, it's your choice but don't be selfish. You may end up hurting the one guiding you and getting them lost as well.

I don't know if eventually the lost can reach someday in the end, but I sure hope so.
