10 reasons why not to get married...

1. The quirks your partner had turns to being exceptionally annoying
2. All the courtship goes out the window - the romance actually did die
3. Forget fashion, those trousers and tee you got 5 years ago is perfectly fine
4. Personal hygiene is what...?  Hello natural hair.
5. Your partner gets annoyed that you haven't read their mind and you should know what they want
6. You forget why you fell in love with the person to begin with and turn your bitterness to new couples on the street
7. Go out? You only go out to get the weekly food shop/work/to put the lottery on
8. Your partner is more interested in what's on the box than why so and so ruined your day/why you've just got fired
9. The wedding promises were nothing but a short contract...you really do mind that you are poor
10. The thing that sucks the most...you were infatuated with your partner for so long you forgot who your friends are - they're no longer there...

This ladies and gentlemen, is not by my own experience but years of observation...
You can call it pessimism but show me a happy marriage...
