Am I heartless

I work 3 days and my husband works 5 days a week. On my days off when he’s working , often he asks me to bring him coffee or coffee & lunch. I tell him he’s insane for asking me to make him lunch, load up our 2 children (2.5&5months) in the car, then buy him coffee and bring it to him. The baby screams all car ride every car ride, and both are working on their schedules. Also, like I already have planned stuff for the day?
