they are the only ones who celebrates 'your' birthday every year for that 2 or maybe 4 years.
there's bbqs, outings and so many other get-together events + also outings organized by school/teacher - you can't forget that memories.
school events, teachers' day, chinese new year, everything which need celebrates - most classes will do something for those special days, and this added as another get-together with things done as a class.
so what's so special about secondary school friends compared to what we have currently? nevertheless, it's those limitless things we all did as a whole which makes that memories unforgettable.
enough said. =)
