I recently mentioned to a CW that my partner and I share a studio. Her reaction: a look of mild horror/sympathy, followed by "Wow, that's not a lot of space for two people" (it's almost 600 sq ft, it is a big studio and frankly, plenty of space). Followed by, "Why?? Do you guys just want to save money or something?"
I just had to laugh. First, it's rent--OF COURSE you try to save money, it's not an investment and you aren't getting it back. Second, this is the Bay Area! It is not that unusual for a couple to share a studio. I mean, okay, it is probably unusual for a couple with two good incomes, but it is not unheard of or freakishly out there (and there are PLENTY of two-income couples who share 1-bedroom apartments, which is honestly not that much different from our setup).
