Dear Annie: My significant other of 20 years is a great guy, and he's been wonderful to me. Here's the problem: "Bob" has an 11-year-old autistic grandson. Every time we have taken "Russell" on vacation with us, it hasn't exactly been relaxing. I am 62 years old and work a difficult full-time job. I'd like a real vacation instead of babysitting a child with special needs. I have offered to take Russell on the weekends, but he says that isn't good enough.
