history: My son is now in college and of legal age for any situation. I feel very nostalgic when I look at him at times. As I look at my 21 year old son_comma_ I often reflect on when he was smaller. Time really flies! Time sure does fly and change is inevitable
current: Yes, that's true. I still can imagine when he was waking up Christmas morning to see what Santa brought when he was 5.
next: Thinking about past events can be very nostalgic
