It's true. I looked it up. Bob came to Costa Rica six months ago today.
This afternoon, when he pointed out to me that it was the 23rd (because the power went out for several hours today, as it did the day after he first arrived), I thought it must be five months, but he assured me it was six and it turns out he's right.
Six months is a long time, isn't it? And of course, as these things always go, it feels like it's been both much less than six months, and also like he's just always been here.
