<human>: Can you provide a brief overview of the text?

My grandfather built a house in 1950 in north of Philadelphia on an acre of land for his family (which included my mother).

In the 1970's, a large wooden cabin-esque house was build 200 yards to the left of the house, and a couple moved in named Stan and Jan Berenstain. They became friends with my grandfather and his family, and in 1999 when my grandparents died, my father and mother took ownership of the house, so I moved in when I was 11.

We got to look in their studio, got cool merchandise, and they were very kind people and excellent neighbors.  It would blow everyone's mind that came over when we pointed to the glowing house down the hill and told them who lives there.  Jan just recently passed away unfortunately, so up until then my family lived next to the Berenstains for almost 40 years.
