I'm a fan (and you should be too) because I've realized the BSBs have been with me in many good and bad moments of my life...
In the good times because it's nice to sing along with them, dancing their music, and also because many special moments with my boyfriend may be described with a BSB song.
In the bad moments it was nice listening to their warming voices, telling me I should go on and that everything will be alright in the end.
Also, I have grown mature listening to their songs, and I realize they have grown a lot too. And it's great to have this feeling they'll always be there, and I'll be their fan "till death do us part".

Luv you all!!
