Lass i used to live with her brothers girlfriend was a vegan & when they came over to my house we had a few words so I politely said let me show you something to explain my point of view. With that i got up & walked to the front door & she followed me arms folded i then courtiously opened the front door for her & when she stepped out i closed it behind her & locked it !! Job done they never called at my house again ?. Atb
