the beach is that sandy part where the land and sea meets
it's quite a popular place for people who like to swim in the sea and need a place to leave their belongings unattended somewhere
they usually leave it on a towel or something
you can eat sandwiches on a beach but it's highly likely they will get full of sand
especially if there is large amount of winds on the beach
the beach also is the setting of several strips
and also a popular setting for comics in general
and cartoons
but i'm not going to list any specific examples
because I cannot be bothered to
