Co-incidences make it look like there is a pattern in what can be random events. People are more likely to be burgled while their home is clearly empty - when they are on holiday. People are also most likely to be using an airport parking service while on holiday. Does that mean the two are connected?

There are only a certain number of parking companies working at each airport. So it is not that unlikely that you and your neighbours use the same company. Put all those things of highly probability together and you get a co-incidence, not a conspiracy.
