Can people who are older teens/ early 20s still do “childish things? ” (read body text) ? /u/Guilty_Letter4203 No such thing as stupid questions

So I’m wondering if it would be wrong to be like 18-23 and still do childish activities on your free Time, like playing tag, or “playing” at the beach and splashing your friends and or just playing in general(sorry if this is weird or worded weirdly)
