MRS. SHALES: They just told me they’re going to share a condo in Tuscon. Arizona! That’s hundreds of miles away!
In the US and many parts of Canada, condo is short for condominium, real estate in which residential units are separately owned, but surrounded by areas which are jointly owned, such as hallways, laundry rooms, swimming pools, and gardens. In other countries this may be known as strata title or commonhold.
It doesn’t seem like a good idea for the quarrelling twins to share a unit together with their new husbands, but Mrs. Shales is just happy they’re a long way from her.
The twins moving away from their mother is an object lesson to Lorelai – if she keeps fighting with Rory, she may end up losing her daughter. Worse, it may come as a relief to her.
