Dear Editor,

We would like to thank Dr. Rujittika Mungmunpuntipantip and Prof. Viroj Wiwanitkit for their interest in our manuscript “Closeness to friends explains age differences in positive emotional experience during the lockdown period of COVID-19 pandemic” [1]. In our article, we investigated age differences in positive and negative emotional experiences and whether the perception of closeness to family/friends and the engagement in daily activities during pandemic explained such age-related differences. We found that the perception of more closeness to friends, but not the engagement in daily activities, explained differences in positive emotional experience.

Dr. Rujittika Mungmunpuntipantip and Prof. Viroj Wiwanitkit questioned about the difficulties in using social network in some areas, such as those in Asia, because of limited infrastructure [2]. We would like to specify that we used the expression “social network” referring to its original meaning that is social contacts with friends, family, or colleagues. We asked participants to report their perception of closeness and, given its critical role in promoting emotional wellbeing, especially in older participants and according to the Socioemotional Selectivity Theory [3, 4], we suggest increasing the closeness to social network. This is possible through phone calls or video chats, during the pandemic period, or encounters in presence, during the “normal” life. Hence, we do not consider the social network as a dedicated website or another application which allows users to communicate and share information. Instead, we refer to the social network as the different groups of people that individuals know.
