The sink sure is drippy

You are celebrating Christmas with your brother and his fiancee, who just moved in together. There is also her mother, helping around the house.

Everything went as always. Your brother Robert, the golden boy of the family, is planning to marry his beautiful girlfriend Sally. They have just moved together into a house. Sure, it's not the most new and modern one, but all the more cozy. Since Sally's father is long dead, her mother has volunteered to help packing and decorations and fixing up everything a new homeowner might need help with.

... Maybe you should lend her a hand?

There are three different opening scenarios. :)

As per request, here's an image of the happy couple:
