It depends on how long the messages have been accumulating. If they have been messaging back and forth for a year or more that's not really alot at all.
You've gotta be careful how far people go to make "dreams" like meeting celebrities come true. I once knew a girl who befriended a make a wish child so she could meet Justin bieber, once she reached her "dream" she stopped hanging out with that kid. Kind of shotty to just use someone like that.
Not you, someone else had posted a comment along the lines of Justin Bieber, obviously, it says it right there". Then as soon as someone else responded ridiculing them, they deleted the comment to make the second person look stupid.
Just in case you were wondering.
