|Question:||The phase: I enjoy going out with my friends...|
|Lesson:||EnglishLingQ - Eating Out, Part 14|
I enjoy... [going out with my friend].
For "like", you can "like to go out with friends" -or- "like going out with friends".
But for "enjoy", you can only say "enjoy going out with friends".
There is of course a grammar explanation for this, but as Steve says it's just a part of the language you will have to "notice" through lots of reading and listening.
