So i was in contact with a WG arranging a meet i knew her general location all is good. txts me address before meet and it turns out she lives in the same cul de sac as a family member, do i risk it?
Yes go for it - no risks what so ever.
Sorry but I smell a shite - you get the full address just moments before and your first reaction is to come on here for advice? You'll already be in the area already milling around the corner or in your car trying not to let your auntie and cousins spot you as you log onto UKP seeking advice.
Even if your query is based on fact don't be an arsehole, how are you going to explain being in the area. The neighbours may know whats gong on as well, you're not just looking out for in the in-laws you're looking out for their neighbours who might just might talk to your relatives, especially if there's a scandal in the street.
