Pissed off inconsiderate $!@#

I'm beyond pissed off! So my niece's of course all ready got my daughter sick and there mom keeps bring them over ever day (she normal dose not bring them over) and my sister in law has been over she was loving on my daughter the other day. Yesterday my sister in law was around my husband and my mother in law working. She comes in today gets as close as possible to my husband to let him know oh she has the fucking flu! So that means me and my daughter have all ready been exposed to it (we live with my mother in law) and I'm freaking the fuck out I'm 35 weeks pregnant and have a almost 3 year old! How could she be so inconsiderate when she knew she was all ready sick with no damn fucking care for us!
