o.0 what is this~

Today I took full public transport back home, took bus to LRT and then bus home because my mom forgot to take her phone so i just took the bus home. While waiting for the bus, a lady gave me her bus ticket. She said take it. I was like shock and took it. Then I went into the bus with her ticket. o.0 weird. Why was she so kind to me? Never before this happen. I was wearing my college uniform at that time. Maybe because of my uniform? But it was weird isn't it?
