First of all the title drew me in - and I just love the positive attitude of your sister - true love can be found at any age and can happen anywhere not just a dating app - my unattached friends talk about how nice it would be to have someone to talk to (as in a companion) as they grow older - I guess as life slows down and there is more time on h=our hands after retirement, we tend to self reflect on the things we missed out on or want to share stories with someone whom you can laugh with - loneliness is indeed an epidemic despite social media - so that may be a factor too
