She only sees guys over 28, so you're probably very correct.
She is actually only around 23 or 24, as when we spoke a while ago, in passing she mentioned she had a 'young persons railcard' so uses that to travel on her 'tours'.....and she does actually look early-mid 20's.....oh, and the thing about older gents she laughs about, and says guys can email her and have a chat before....just she said she has had crap experiences with younger guys.
You can tell I'm a fan - seeing her for the 8th time before Xmas, for my kissing and sucking fest!
