I am over 70, and most of the women my age in my Parish are much more disabled than I am, or come from either Nursing Homes or Assisted Living. My closest friends at my Parish are all 30 - 40 years younger than I, and believe it or not, we are friends. I have become an “adopted grandma” to several, and I find that they like having an older woman around who has been there, done that, and often ask questions. I also volunteer as a Eucharistic Minister, Altar Server when the young families are on vacation, etc… You might be surprised how many of these older women have no children living within a few hours of their home – most of their kids are scattered all over the country, and they’d love to be involved with a young woman just starting her marriage and family. They’ll soon adopt you as their “daughter” or “granddaughter” and since you are young and able, you’ll find the Priest would love to have the help of a younger couple at the Parish Office, at the Mass, as Sacristan, etc… If most of them are older, they don’t volunteer as much in the Parish, often due to ill health or mobility issues. Talk to your Priest about how you can become involved-- he’d probably love to have some younger people to assist him with a lot of things, even as a Church Secretary or office help at the Parish, until you have babies at home that will take up your time. And, you’ll find that the older ladies will love having a younger person to talk to about faith issues, hymns, prayers, and maybe joining in or helping to start a Rosary or Prayer Group!! My Parish is also in a small town, and we have no Deacon since the last one died about 10 years ago. Over half our Parish ladies are in their 30’s or younger. The rest are older than I am! The older ones can’t do much anymore in the Parish, so I attend the Mass at the Parish Center, which is easily accessible for those using canes, walkers or wheelchairs. In this way, I am actually one of the “young” ones!! That’s how I finally met some of the women who have teens and tweens who go to the old Church (over 120 yrs. old), which is not accessible to the handicapped. I made friends in the younger group, and also go to an occasional lunch with the older ones. I find I gain a lot from those in their 90’s (lots more life experience) and get my enthusiasm for the Parish from the ones in their 30’s and 40’s. We all get together (all age groups) for our Prayer Group and Rosary as well as for the luncheons.
So volunteering is definitely the way to meet people. After you’ve shown people that you are pretty reliable, talk to whoever needs to be spoken to about starting a group, like an adult ed class during Sunday School. You will probably start meeting parents that way and it’s good icebreaker for being able to talk about one’s Faith, which is not really a strong feature of most Catholics
