Every time when i mix with people younger than me, not only i feel a little older it also brings some old memories. I would think, if i were at their age, what would say or react.
They are still young although surprisingly mature (maybe it's my underestimation), i feel they are capable of a lot of things. That kind of startle me a little since, i'm older but had achieved nothing much so far. Not only that, i were not that mature when i was at their age :) that's why when they said i look younger than i am, i sort of think, that's because i'm not that mature you know .
Of course, mature is just an adjective. One can be mature in one thing but less in others.
After mixing with my young friends i am inspired to write the following paragraph.
