Everyone benefits from meeting other people
Meeting both new and familiar faces can have a positive effect on the contentment of someone being cared for at home on a long-term basis. For someone undergoing a short rehabilitation period, getting out and about and having visitors can help speed up the recovery process.
In the care plans we draw up with our clients, we always try to incorporate some elements of socialising, catered to each person.
Although everyone has unique needs, and physical abilities may differ greatly, we find that everyone benefits from occasional (and preferably regular) socialising. A social event can be something to look forward to, enjoy at the time and then look back on and reflect on.
If someone is wheelchair-bound, that's not a barrier to us. Even someone who is permanently bedridden should be able to receive visitors at home from time-to-time. This brings a little of the outside world into their life and can make a big difference.
