It was a while before midnight. Me and my roommate were in the hostel's night canteen, ordering food. Two girls were asking the staff for a lighter to light birthday candles for their friend's birthday but the staff were unwilling to give them one. I thought it would be heroic to give mine so I offered it to them. They asked where my room was but I told them they could keep it.
Being a person who doesn't usually speak to strangers, it feels really good that I aided in their small celebration.
