HOLY. Ann needs to hit some reality here. Seriously.
If she thinks a stranger she 'finds' is going to 'fulfill her travel dreams' then she is in for a rude awakening.
but honestly, it is her life. at some point your advice is either accepted or not. Let her do here thing after you had your say.
Ann is doing this all wrong. But it is her choice to do so :)
I know it is bothering you obviously to see her run off in this direction, but at some point you must let go. adults have the right to be stupid as another said.
