Can't sleep

It's late but I can't sleep. My sister, who has been looking for a job, has an interview for one in another state. I've been thinking about what it will be like if she moves away. It's been a while since I've had to be out and about by myself and I forget most of the time what it means to not see well because she sees for me. Yes, I can read most stuff on the computer - I can make the words very large and I can control how close I can be to them, but that's not usually possible out in the world. Imagine what it would be like to not be able to read street signs, the bus schedule, a menu, price tags, bulletin boards, cross-walk signs, cash register read-outs, the titles on the spines of books at the library, the numbers on a telephone or in a phone book. Imagine not being able to drive, not seeing cars coming when you cross the street, not seeing who among a group of people is talking to you, or if you are indeed the person they're talking to, or if they're male of female, of they're smiling or frowning, imagine getting lost. And not seeing things will be nothing compared to the loneliness. I hope she doesn't move away.
