I drive my dad everywhere he needs to go. He needs a walker and oxygen. He refuses to get a handicapped plate because they are for "people worse of than I am." However, when he feels bad, he tells me to park in a handicapped spot. I won't do it and it makes him angry. Also, when he talks to other family members he overstates his ability to get around. He is embarrassed by his lack of mobility but it's getting progresivley harder for me to get him around. Suggestions?
