my dad and i were talking about the past , just reminiscing a bit . i 'm going to miss these times . i miss my dad .. been so long . what did you guys talk about ? mostly just my childhood and some of his . his mind is going quickly , there wo n't be too many more conversations like that . my mom had alzheimers .. it sucks !
The impending loss of the father's cognitive abilities due to aging triggered the sentimental feeling.
