my friend's family and a bike...

I am sure; it was very nice to see my friend
Who was very happy in his life before his marriage?
And he was very comfort in his bike to sit and in ride on it.
Its seat was very comfortable,
And he can easily move on it, forward or back.
But he started to share this comfort seat when he got married
And his wife was not fat at all, and they managed it very well
They traveled days and years on it with that comfortable seat.
But surroundings are not even better, they got two kids
The first one is a daughter and a son
But my friend never stops riding the bike with family
They are on the bike every day to travel anywhere else
And now I found, my friend is not happier than before
He cannot sit on it very well, and is not comfortable now
He is talking about small seat of his bike...
But he is not aware about his kids who are growing every day…
