for the past couple weeks, my mom has been meticulously planning a surprise birthday party for my sister, whose birthday is in late march. my sister loves surprises and my mom is trying to be extremely secretive about this party in order to really catch my sister off guard. my mom doesn't let anybody discuss details of the party while my sister is in the house and even created a fake email account to plan the party, just in case my sister somehow sees my mom's emails and discovers the surprise. as you can tell, my mom is really serious about this surprise party and wants to it to be a mind-blowing experience for my sister. as a result, my mom as booked a popular dj, a fashion lady (or something like that - i don't know the actual title) to give all the girls at the party make-overs and whatnot, as well several expensive birthday presents. the next step for my mom was to discreetly invite a bunch of my sister's friends (i think about 10-15 in total) by sending an email (using the fake email account) to each friend asking if they are available to attend the party.

here's where i get involved: 

i'm on facebook today looking at pictures and scrolling through my news feed just like any other day when one of my friends suddenly chats me. 

him: "dude i got a weird email from your mom. i think she sent it to the wrong person."

me: "oh really? what is it about?"

him: "it's an invitation for some girl named samantha to attend your sister's birthday or something. how did your mom even get my email address?"

me: "hahaha. that must be for my sister's surprise birthday party. i have no idea how my mom sent *you* that email though. i'll go ask her."

immediately after this conversation i try to ask my mom why she sent my friend that email. so usually when i try to ask my mom for something and she is in the living room and i am on the second floor of my house, i just yell really loudly to get her attention. so, without thinking, i scream, "hey mom! why did you send an invitation to *friend's name* for *sister's name*'s party? i think you meant to send it to samantha!" while i was so caught up in why my mom sent my friend that wrong email, i didn't realize that my sister's room was right next to where i was standing. i take a peek inside the room (somehow hoping that my sister didn't hear what i had just yelled) and much to my dismay, my sister is sitting on her bed where she was definitely able to hear everything that just happened. 

oops. needless to say, but my mom was pissed.
