I actually think Gal got caught up in her passion for socializing. And socializing is good. Socializing is a need that goes unfulfilled by choice sometimes, but it is a need. I think she just caught up in thinking that is related to a need for marriage too.
And truthfully, marriage becomes a need too for some people. I was content to be single. On our first date, (which should be included in "Things not to Say on a First Date," but given I'm not your normal person either, it worked for him lol), future hubby told me he was the kind of guy who needed a wife. His need was real.
Honestly, I neither needed to be single nor married, until I met him. And once I met him, I needed him. So theories on if I needed marriage or not all flew out the window that night.
BUT, I honestly think Gal is one of those wants-to-be-married types, who got passionate about her desire and overstated her case, not out of unkindness, but because she got caught up in her own desires enough that she momentarily forgot the other side of the story.
That one happens to all of us.
As far as those who don't think they need other people goes, my dad is still unaware that despite him never wanting to be around anyone, he's very fortunate that desire was ignored. He hates all the nurses, doctors, aids, and janitors at the hospice. He thinks all the other residents are 1-51 cards short of a full pack. But he has absolutely no idea that he's 51 cards down from the full pack too. Antisocial or not, he is being kept comfortable and alive by those very creatures he always tried to avoid -- people.
So, Gal isn't wrong either. We do need to be social. We can't live as long without other people.
