My dear Stan, did you ever did a trip like this?
If yes, i don't understand your post, for that matter i never understand
your irony, or should i say i don't need it.

If no, how can you put yourself in his shoe's, how do you know how it feel
do be travelling for 1.5 years.... Can you think for a second, that a person
would do everything to contuinue just a little bit.....

He perfectly know that he may have to go back home and start back is normal
life.... he doesn't need you or others to tell him so.

So get out of that thread if you cannot help.
