"I love you, so I want you to be happy. And for that, you'll need to get married..." "...I know." sigh
Honestly, arranged marriages I can swallow, although, with some difficulties. But, this notion that female happiness lays in getting married (to a male, obviously), and then, in all likelihood, having children is just... Well, I detest it, in any case.
That being said, I actually liked this one. Probably because the grandmother provided an explanation for her choice (even though I find the explanation to be absolutely ridiculous, and childishly naive, but still, most stories of this type just stop after those sentences about "finding happiness"), and is not actually encouraging her granddaughter to do the same. If anything, it looks like she is subtly cheering them on in the exact opposite direction she herself took.
So overall, old, recycled idea, but with added actual explanations and debate what the right choice, or a choice without regrets is, and to actually have a grown-up person, an elderly one at that, supportive of the relationship, is kind of a rarity. All in all, I liked it.
Bittersweet maybe? But Grandma was happy with how it turned out, how can I then be sad?
She never actually says she is happy with it all. To her granddaughter's accusation of a "loveless marriage" she responds with "We raised three children. Isn't that enough?", and that bit about it being love in a broader sense. It seems to me more like she is putting forth rationalisations, rather than anything else. Also, she says she was proud of her choice. Not happy, proud. And, in the end there is this: "Maybe there's no one right answer. But there is most certainly a path with no regrets. I pray that they will be granted the opportunity to take it." Considering how supportive she seems to be, it stands to reason that the "path with no regrets" she hopes for them to take is the one she herself did not take. It also implies she regrets her choice.
Now, I am not saying she is miserable. She clearly managed to find a measure of happiness in her life, being it from her children, her grandchildren, or perhaps even her husband. But I would not say she is happy with how it turned out, since that implies she somehow made the right choice, and it all turned out well in the end. She would hold no regrets then. No, I think it is better to say that she made her choice, possibly a wrong one, but still managed to find some happiness in her life afterwards, regardless.
