An earlier testimonial said "i met a great guy ... if i had looked at his profile first we prob wouldnt have got together."
Seems many people have pre-conceived notions as to what will excite them and so they don't open messages. So many opportunities lost.
So go with that earlier testimonial and open the message. You can delete it within seconds if it is way out of court ... but you might just find a goldmine like she did.
