So, it's summer, and beach parties are starting up all over the place.

My backyard is the beach, but I have never been to a party. However, I see parties happening near my house all the time.

What should I do to get to these parties? Should I just go over and say, "Hey, how's it going?" or should I bring some booze of my own and say "Here yah go" or what??

Take a crate and just go introduce yourself to a few people, usually people just turn up and join in anyways, get a few mates to go along with you and it should be easy :) hope you have fun.

Even if I don't even know any of them and they may be 1-3 years older than me (I'm 15)??

And crate? like for sitting on?

And is it common courtesy to bring my own booze, and perhaps a little extra for the group?

Will people mind me and a couple people who weren't invited just walking by and chilling?

Walk over and say hello. Introduce yourself, if they seem like decent people, or fun people, then let them know you have booze and maybe some food to toss on the fire at home and will be back after you grab it. Living nearby means that you can test the waters before you jump in.

Take a nice sack of weed with you, or at the very least have a few blunts pre-rolled before strolling over. Trust me, as soon as they know you have that with you....they aren't going to care in the least about you "crashing" their festivities.

"A friend with weed, is a friend indeed".......its that simple and words to live by.

there's always randomers at party, how dya think you find a new lass?

i lolled when you said a crate was for sitting on.
