Fragmentation.

I can support you
(it doesn't mean
I'm strong)

I can stop myself from crying
(but it doesn't mean
I never fall apart)

I might barely be an adult
(doesn't mean
I'm an inexperienced boy)

I act tough when
I'm not
Sad when I am
Lost
When you don't know
How things will work out

I am serious
through my funny faces
I am happy
through my tears

Young but wise
Smart but foolish
Such a stereotypical
paradox

In the end:
I'm but a figment
of your fragmentation.
