"Mother's Heart" ends with "My nose is sore". Please tell me what it feels like. "My nose is sore" because.

Sour nose is a physiological reaction caused by psychological activities ~ generally, it is a feeling of wanting to cry because of scenes or words such as sadness ~ touching inner emotions ~ This is a silent and deep rational touch ~ different from crying and sadness in the usual sense ~ that is, "harmless sadness".

I haven't read the article you said ~ but from the analysis of the word "loving mother", it should be that the ordinary and great mother silently bears the weight of life or the multiple hardships entrusted to me by fate ~ All the sufferings are carried on her shoulders only for the peace, happiness and happiness of me ~ After unexpectedly discovering that everything her mother has done for herself is so difficult ~ Grateful ~ Self-reproach ~ Distressed ~ Ashamed, and so on ~ Feeling is in.

The above is my humble opinion ~ I hope I don't make you laugh.
