Not sure how old you are, but guess you're on the young side. If you are working, you should have no trouble meeting people & finding stuff to do. If you're over 21, there are a lot of locals hangouts where workers seem to congregate. Sunday night is popular, because a lot of them are off work then. If all else fails, check out the event calendar on this site; it's pretty extensive.
OC changes a lot week to week. Lots of college students just off from school in May/June; then the "Junebugs" later in the month; HS Seniors who go crazy here until they run out of money or are arrested (or both). Then around the 4th,more families, firefighters week, etc. Again, check the calendar for what to expect.
Word of warning; our plumber moonlights security at a joint in Dewey Beach and says he spends way too much time in court, for having to testify for this or that, fights, etc.
You should get some other advice from the good folks on this forum
