Despite what some people may say about reaching a "mature" age and leaving your previous childish behaviors behind, there are certain "immature" behaviors that, although I may participate in them less , I still find them pretty enjoyable. Like...
1. Blasting music and dancing around in my room by myself
2. Reading trashy gossip magazines
3. GOSSIPING, in general
Even my mom still likes to gossip
4. Eating peanut butter right out of the jar by dipping my finger into it
And eating messily when I'm alone, in general
5. Trying on new outfit combinations and trying new makeup trips late at night when I'm bored
And staring at myself/making weird poses and faces in my mirror
6. Imagining myself dating and marrying a celebrity...imagining myself being a celebrity
7. Reading nonsensical articles such as "subtle signs he's into you" or looking up a guy's astrological sign to see if we're a good match
Note: This type of behavior is surprisingly not productive for your love life
