Well SB she is either extremely rude, or extremely brazen.
But if I were you SB I wouldn't send a dime, yeah she says it's for her parents to spend a weekend at a B&B. But yet how can you be totally 100% sure it's for that. Heck this gal just may be pulling a scam.
I've heard other tales of people being the victims of scams pulled by family members.
Now don't think I'm actually saying anyone in your family would pull a scam, cause I'm not so I apologize in advance if you took it as such.
