My sister in law almost burned down my house by setting pizza boxes on fire in my oven. She used a fire extinguisher and I mean there is residue from the extinguisher everywhere. It's so bad it got my daughter sick and now me. I took my daughter to her grandparents and our dogs to daycare so we can deep clean the house. My sister in law said she would help but literally she woke up and left and said she was going to Portland. So my husband called her and said that this mess is her responsibility so she needs to help clean the house. If she's not back home in a reasonable amount of time she can find somewhere else to live. Literally I just did all my laundry and it was folded on the table now I have to redo all the laundry in the house and scrub every inch of my house so my daughter and dogs can come home. My husband's sister is all pissed off because she has to clean the house and is posting on Facebook that that she has no where to call home. This bitch almost burned down my house and got residue everywhere. I understand it was an accident but the least the bitch can do is help clean the mess she made and take responsibility for her fuck up. Who doesn't look in the oven before turning it on its common sense.
