OK so every time I bring my boyf around to my moms house she assumes or expects for both of us to do stuff for her.

Ex. If we go get something to eat she assumes we're bringing something back for her.

Ex. She assumes he's gonna pick her up from work. Its a 10-15 min walk to her job from her house.

Am I wrong to think that, even though she's my Mom, she should at least ask?
