being a grown up 
Today I will hopefully take the last step to being a true grown up - buying a house. Only took me more the *grumble* years to do it. While all of these things are not *needed* perse to be a grown up. To me they are stepping stones along the way. Let me know if I missed anything on my checklist for it.
1) pass 18yrs old
2) have a car that runs regularly
3) have a career rather then a job
4) married
5) kids
6) buy a house
7) owing more then you make in a year
