It is terribly hurtful to be served papers be it at your home or place of employment. My attny had a saying that I really tried to remember ALL the time.... "you only have to get served once", "you only have to sign this document once" and so on.
It is a horrible feeling. It stinks out loud. The silver lining? You will NEVER have to experience it again. It is now an event for the history books.
Today will be a good day for you. You have tons of support here and lots of good and caring thoughts being sent your way.
And, while this is a leap perhaps she had you served at work so the children did not have to witness a process server coming to the house. Either way it is a terrible feeling but remember - it will NEVER happen again!
