Not wanting to Steal Fireblade7's thread (met him yesterday, nice bloke with some good quality bits for sale too) but what are you frightened of ?
What have you done that stops you wanting to receive phone calls ?
Are ashamed of something ?
Why wouldn't you want people to phone you ?
Do you surround yourself with arseholes ?
Do you think there is a selection of people out there who are looking for middle aged men with landrovers whom they can prey on ??
In fact there is a thought - is that what happened to you ? Someone got your phone number from a forum and phoned you up to ask if you'd even been caught ****ing behind your spare wheel, or would like to be ?
I imagine that would make you neurotic ??
Perhaps I should start a thread "what did the pervert say to a middle aged bloke with a landrover ?"
