And So It Goes (2014)

Nobody likes self-centered realtor Oren Little, and he prefers it that way. He's deliberately mean to anyone who crosses his path and wants nothing more than to sell one final house and retire. His life turns upside-down when his estranged son drops off a granddaughter he never knew existed. Suddenly left in charge of her and with no idea how to take care of a child, he pawns the girl off on his neighbor, Leah -- but he eventually learns how to open his heart.
