What do you count as an adult? I was the weird one by having my own place. Every &#x27;adult&#x27; I know had roommates until they found an SO and moved in together and&#x2F;or got married. These people all made enough money to live alone, but preferred spending money on other things. I also do not live in a super expensive place. A 1br apt. goes for ~1200 in the trendy spots.
