I hate to be the hobby police here, because I don’t really have much by way of “hobbies” in the traditional sense, but gentlemen:
“Talking to friends” is not a hobby. That’s how normal people socialize. “Going to the gym” is not actually a hobby either, unless you’re training for something special or bodybuilding.
This is the section where you can sound mildly more interesting than all the other nice, smart, professional boys out there. Please make some kind of effort!
