If a girl has been calling for hours trying to reach Joey, and argues that she has the right number and she knows Joey is there, DO NOT -EVER- tell her that "fine, yes, this is Joey's number and I'm his wife and we have 3 kids and who the hell are you?". Because she is 16, and Joey is 16. And their parents will call for hours calling you a child molester, demanding a paternity test on those imaginary children.

When texting a girl you're interested in, it is best to make sure you're texting the right person. Your sister will be confused at first why you decided to text her out of the blue, and things will get a bit awkward before she realizes your mistake and clarifies who you're actually talking to. #LFMyBrother'sF

Even though the only reason you ever use your cellphone is for notifying your parents of where you are, always be careful to answer with "hello". Although unexpected, it may have been the hospital's head of the volunteering department, and the lady who has the final say on if you get accepted or not. Answering the phone immediately with "Mom, I know! I'm right outside the door!" will most certainly result in said department head laughing at you. #LFMF

If you call the police by mistake and them hang up, don't call it again to say that you're sorry. #LFMF

When making an appointment to see a new doctor for the first time, be absolutely sure you have the right number. Otherwise you might end up telling a very bewildered stranger all about your embarrassing personal problem. #LFMF

When jokingly texting a good friend that they she has very lovely boobies; check that you're not texting your co-worker with the same name, and that the coworker isn't walking into the office at that moment. #LFMF
