But what about sleeping Brick video. Even you believe she lives in D apartment with him and took video of Brick sleeping in the morning? Thanks for opinion, I think this M thing is getting out of hand – see Extra footage:(I really would appreciate your opinion.

What extra footage? I don’t think she lives with David. But I think she spends her day there watching, walking and sitting Brick at David’s apartment. So yes, she takes pictures and videos of him. Who cares?
I think she has a deeper connection with David’s dog than David himself.
