My two cents ...for what it is worth.
 
1) I believe that what took place between Lauren's little bee and the larger young male was not accidental.  My theory it was intentional.  It isn't like anyone .. even inexperienced isn't going to know when their bitch is in heat. 
2) I believe the story about "accidental" was made up in an attempt to avoid chastisment for what the OP would know YT members would feel was careless and irresponsible. 
3) OP then came to YT with her "story" hoping to hear.." well, whats done is done.. lets talk about your cute puppies. I believe the OP's thought process shows a level of immaturity on many levels.  I don't believe she has been out in the real world for long..if this situation has her missing work.  This is the selfish act of a child wanting their own way and when they don't hear and get what they wanted.. they throw a fit and tell you that you are being mean.  I know that is what my children tell me when they don't get their way... but again... this is just my two cents.. and I am new to the site..so what do I know?
