You may be wondering why your parents who have been supporting you a lot since your childhood are suddenly behaving weird. Though you are busy with lot of work, handling many projects why do you think they would compel you to move them around once you are back from work. Don’t you think you have also troubled them the same way when you are in your childhood? Soon after they returned from office, you would have ignored the care taker and would have been after them and would have demanded them to pamper you.
So, now it is your turn to serve every demand they make to you when they have retired from their job and have been struggling hard to move around because of their damaged knees. These are the same knees that ran with you when you are young to play with you and to support you on every naughty activity that you did at home. If you think you should let them be proud of being by self even in such tough situation then it is always good that you buy the mobility scooter that would help them to go from the room in which they are asked to stay to the room they want to go like the reading room or the living room.
If they are not happy with you and are not talking with you or else not even having the food that is served to them, then do not think they became as psychos. No they are just expressing their grief of staying at one single place throughout the day. With the scooters that you buy for them whole day they would be moving around and could even take care of themselves like serving the food by themselves thus having the proud feeling of not relying on others in their old age.
