I can't convince a client to do something she doesn't feel comfortable or interested in doing, of course, and discussions about eating well and stopping smoking (which Keisha and I have had) usually don't make a person make a change. I don't have to go much farther to finding friends and family who choose to continue smoking, for example, and it doesn't matter what others say. On the other hand, Keisha also complains about loneliness and her difficulty in making friends. Years ago she was diagnosed with mental illness. I believe she has a developmental disability as well though paperwork doesn't reflect this.
And for folks like my client there could be a positive side effect. Making a friend with someone in her building. Someone who would knock on her door to get her out and active. One friend and a sense of companionship would be great for her. Some people find more motivation in exercising, quitting smoking, or just leaving their apartment if they're meeting a friend. But even just for friendship, just support. One person would make a big difference.
