First day of School!

Oh dear! Today was the first day of school! Now I'm primary 5.
They say p5 is very hard! What if I get a lot of homework? What
if the homework is very hard? What if my teachers are very strict?
( I haven't met all my teachers yet. )What if I cant go for any more
butterfly trips. Hey wait! That reminds me my mother is thinking of
signing me up for the nature society! Well only thinking of doing
that. Apart from that, there isn't much on the bright side.

Help!

p.s. : Now my sister is secondary 1, even more to worry......
