These are the types I can think of:
 
The Whirlwind – The status of the ‘whirlwind’ can only really be achieved in late middle age. The Whirlwind generally does not live close to home; their visits are sparse but enthusiastically executed. The whirlwind’s visit is a flurry of organising, tidying, cleaning, planning and treat giving. Much is achieved in a Whirlwind’s weekend visit and parents are left full of gratitude, but slightly shell-shocked. In all honesty, parents are not sorry to wave off the Whirlwind, though do enjoy sharing all that has been accomplished in a boastful manner with neighbours and friends.
 
The Plant Pot – The Plant pot is almost the polar opposite of the Whirlwind. When they visit they plonk down on the sofa, comment on dust on the TV stand or wherever it may be, and expect to be fed, watered, sheltered and spoken gently to for the duration of their stay. They thrive under these care conditions, but ironically the parents being visited don’t.
 
The Well-Meaning But Misguided – The Well-Meaning But Misguided’s intentions are sound, but they are unlikely to achieve favourite status. The Well-Meaning is full of positive and helpful suggestions for how to do things differently and better (i.e, their own way). This ranges from how to hang the washing out, to what to buy at the supermarket, to where to position the sofa. These suggestions are usually good ideas but not always well received. The Well-Meaning’s But Miguided’s nickname, used by the parent in their absence is the ‘Knobby-Know-All’.
 
The Egg Sucker – The Egg Sucker is likely to be in their early twenties and be entering a new phase of financial security and independence. Their skillset includes giving advice on everything from marital relationships, to how to cook dinner, to how they themselves could have been brought up better. The irony of this is usually lost on the Egg Sucker, but not the parent. The Egg Sucker can be extremely irritating  
 
The Sponge – the Sponge, otherwise known as the Pacifier, knows more gossip about the parent’s friends and neighbours than they themselves do, due to endless hours of being talked to. If The Sponge has a qualification in Counselling and can appropriately add questions to the conversation, such as  “How does that make you feel?” their title changes to The Listener.  The Sponge’s visits provide a valuable outlet enabling parents to vent. The Sponge often feels saturated and needs to wring out after visiting their parents.
 
The Clown – The Clown sees their role in the family to entertain their parents. They are not above performing a bit of a show, song or dance even when in their late middle-age. This causes concern amongst parents who often question post-visit, if the changeling child really belongs to them.
 
The Helper – The Helper has very good intentions and hovers around as parents prepare drinks and meals and offers to help. The Helper’s weakness tends to be that they think parents are incapable of doing all the every day activities that they complete all the time the Helper isn’t there. The Helper can be known to overstep the mark causing both confusion and offence when stepping unintentionally into Critic or Whirlwind mode.
 
The I’m Gonna Soon – The I’m Gonna Soon has a deep need to impress their parents and isn’t above a bit of exaggeration when talking about their accomplishments or achievements. For example, the I’m Gonna Soon would equate modest sales to the likelihood of becoming the next J.K Rowling. The I’m Goona Soon has been known to present themselves as The Helper and frequently offers to do tasks around their parents’ house. Sadly though, this never gets beyond the discussion stage.
