I think some of the negative comments are due to a too rigid interpretation of 'arrangement.' I'm not talking about a formal arrangement but more like trying to make a dea,l kind of like a business merger, if everyone is happy with the particulars then the marriage goes forth.
If you're interested in something like that then it's best to make it informal. It's obvious enough when a parent is interested. I recall meeting a mother of an SSPX priest who introduced herself to me and was very friendly towards me. Not long after her youngest daughter came up to us pushing her grandmother's wheelchair. Now you could say I'm wrong to suspect what her interest in me was, however, when I told her my age she was very much shocked. Her youngest daughter was little older than 20.
Now I could be wrong about what her motives were, but when middle aged women with grown daughters take an interest in getting to know me - hmmmm, when has that happened? There aren't many contexts.
There was another who came up to me and interviewed me several times, but that was after I'd already met her daughter. I'd told her daughter my age and job circuмstances (which I said were poor) from the moment we met - the first thing she asked me was "what do you do"
Her mother, however, was not informed of my age, and finally took the opportunity to ask me a few weeks later. You should have seen the look on her face.
