In the evening, there are no distractions. The night may bring long hours of empty or unstructured time.
Whether it be your spouse, child, parent or anyone who lived with you, to help with a meal, watch television or talk about your day, it can create much loneliness in the evening.
Darkness has an impact on mood and motivation. When it gets dark earlier in the season, it can lower your motivation to want to participate in evening activities.
