I took my 8 year old grandson home to his dads tonight after a party. It was dark so I helped him across the road, through the gate and waited at the side of the house until I could see he was safely in. However when I returned to my car my ex son in laws dad was banging my car window, swearing shouting n threatening me cause I stepped on his property. I was shaking. Im so worried as my autistic grandson has to be dropped off to the same house tomorrow and hes told me god help me if I set one foot on his property. Im not leaving my autistic grandson to find his own way to get in there house. Any advice please. I cant speak with the dad as he blocked me on everything after I had a go at him cause he keeps calling my autistic grandson fat.
