Wrong number???

Okay....so I am a dumbass,but first I will go back a hair so this story is complete.
My sister and I are taking over Christmas dinner for my mother, she is older now and is just tired.I actually am the one that volunteered to have it at my house (I'm going to have to clean...shit!!) and thank God my husband was on board too or that would have been bad.
Mom has been cooking dinners at least three times a year for oh...let me see..over fifty years?? YEAH I'd get tired of it too. You spend all this time preparing every meal from scratch (because that's how they do it-old school) and family comes, gobbles it up, drives you crazy and then leaves.Oh, not to mention that's the only flippin'assed time you basically see them all year.  Kids.
BUT anyway, my sister and I have been conversing on the phone about this dinner, and how we are going to bring it together with what people will bring, etc. Thismorning I decided to hit her up and let her know that I had talked to our brother, so I texted her and asked her if she was as work and she said no so I called her....
Okay.First of all-nowadays we have people on intstant dial on our phones.I myself have a few numbers that I know by heart, but mostly I just push a button on my damn phone to call them. Perhaps I should pay attention??
When I called my sister, I used the house phone and actually punched the number in..so if I got it FROM my phone it should be right---right?? I don't know what the hell happened, but the person on the other end of the phone sure didn't sound like my sister.I was pretty sure I heard a few cats in the background meowing-and my sister has no damn cats!
I went on for a minute,with the "Oh I texted you and you texted me back-wanted to talk to you about christmas dinner-blah blah blah-".The whole time I'm thinking 'this person has no fucking clue who I am and  I have dialed the WRONG number because I am a MORON!
So what did I do?? I HUNG UP..That's right. I hung up.I felt so stupid and rediculous I had to get the hell out of THAT situation while I still had any dignity.Do you know what this person did???  SHE CALLED ME BACK!!?? Yeah! Holy shit-she called me right back and says "Yeah sometimes my phone dies"  I couldn't believe it!! WHY did she call me back if she doesn't even know WHO the hell I am to continue this empty conversation??
Are people really that desperate to talk on the damn phone???
Well I regained my curteous composure and went on about why I called for a second and politely let her go. THAT WAS NOOOOT MY SISTER....
WTH?? Am I in the flippin assed twilight zone today or what?? I just don't know. I have several days like this I must admit, but this one was particularly weird.Who ever  this person was, she was very kind to a moron misdialing...or she thought a crazy person got ahold of the damn phone.She actually went along with me and didn't embarass the shit out of me.Whoever she is, I thank her HAHAHAHAHA!! GOD I am a moron!!
So remember.We are not used to PUNCHING in people's numbers anymore to call them..beware when you venture to use your brain and your landline together.You could be a bumbling misdialing moron on the phone. Just saying. Also I STILL have to talk to my sister. Shit.
