LED

My kid loves LED. He especially likes to watch the LED with running words. The LED inside bus is one of his favourites. He can watch it all along a bus trip enthusiastically. What's so interesting about it? I wonder.

Today I missed my kid quite much. When I took the bus home, I thought about him. Thought about him watching the LED if he was with me inside the bus. Nothing else beside the LED. No one else beside my lovely son.
