In laws..

I'm so pissed at my sister in law. She asked if she could take my son overnight & for today so she could go hang out with a friend who just recently had a baby. I texted her all day today & she ignored me all day. I asked her if she could keep him till 6 when her brother got off work because I had surgery last Saturday & am still recovering, nothing. I asked her if she could atleast let me know a time, nothing. Asked how the playmate went, nothing. I said okay just let me know when your on your way. Didnt hear a thing until she's literally bringing my son & his stuff inside & then walking back out the door. She didn't tell me when he last ate, she didn't tell me how the playdaye went, not a single word. So I texted her & told her it's not happening again but now the whole family is pissed at me.
