2. When people spell 'I love you' like 'Iloveyou'. With no spaces in between. Same with 'thank you', 'you're welcome', etc.
3. When People Type Like This.
4. When people are too mature for their age.
5. When people are underage for a website; for example, if they're on a website like YouTube where you have to be 13 and over to join. They will say they are 13 for over a year, or they will say that they are underage for the site, and they will say that they joined because they are mature enough. If you were mature enough for YouTube, you would wait until your 13th birthday!
