open/close

For those who have doubted the utility and raison d'etre of Twitter, witness the Tower Bridge's Twitter posts:

I am closing after the SB Lady Daphne has passed upstream.
I am opening for the SB Lady Daphne, which is passing upstream.
I am closing after the SB Gladys has passed upstream.
I am opening for the SB Gladys, which is passing upstream.

It's sort of endearing in a way that's difficult to explain. Perhaps any personification of an inanimate object lends that personified object a certain quotient of cuteness.
