pitstopbunny, I work as a carer for the elderly and I see myself being very fortunate to be able to help these kindly people on a daily basis, we laugh with them daily, see them through the torments of alzheimer's and dementia and help them through many physical and mental problems. Being a carer is probably the most rewarding job I have ever had (the worst paid though) and would happily do the same work voluntarily!!
I am 49 by the way!!
No such thing as too nice, I promise!! you will be rewarded a thousand fold just by helping that elderly gentleman.
Most of these elderly folk would just appreciate a good natter, find out what he done during the war, where he lived as a youngster, what job he and his father done, you will learn so much and he will enjoy your company.
Good luck!!!!!
