My mother is a single mother and a senior citizen, she had gone through phases of life with boldness. Along time gone by and gained age, one by one of her immediate family started to disappear from her life, slowly without realizing, loneliness started to kick in. Changes in attitude also emerged, she is most likely to spend time alone by herself, easily offended, frequently complains like a child, and often reminds her daughter repeatedly of minor things in daily life and then in another moment she is there strong with all of her power doing the small tasks of an every day.
One thing for sure that I am aware the most is, her habit to collect things that have something to do with the past, preserving memories. A bunch of old pictures of her beloved ones along with stuffs that is not necessarily important in life but has sentimental value instead, represents a reflection to fill that empty space over her lonesomeness.
