Because your parents had strange rules around them?
For me it's:
Showering daily
Using 'too much' shampoo and shower gel etc.
Washing my clothes and bedding before it could walk to the washing machine by itself.
Enjoying a spontaneous trip out for lunch/a bit of shopping with the kids.
Eating my evening meal later than 5pm rather than planning the whole day around making sure your back in time for 5pm.
Buying my kids branded items for school (not the cheapest version off the market)
Sure there are more...what are yours?
