Because I live near the beach. To me, this makes a lot of sense The problems of the season is actually a name that fits the artwork wow. There will be tonnes of jellyfish during a summer season so makes sense.
lucky you!!i live in an island ,named Crete! the beach is a few miles away but we see it from our windows! I'm aware of the jelly fish season but since 10 years, we haven't seen them!!dunno why!! maybe they don't come here in Herakleio! they can be found everywhere in aegean sea and in mediterranean but not here any longer!and the water is crystal clear!! maybe the drifts/streams has changed!
