I put Other because its stereotypical to suggest booze even tho alot of homeless ppl are crackheads and alcohlics not all are. Such as all housing agreements (except government owned houses such as section 8 houses) if you dont have lose your job they kick you out. Here is a situation that fits that situation:
John has a job he has been with for a few decades, and makes an average amount of money then gets layiad off (Spelled that wrong) . What then he has no job now normal ppl could go to a parent's, friend's, or a mate's house but what if John had got laid off and he lived in a state away from his parents', hes around 30 and his friends all have families and he has no mate . Hes homeless... But I see how most ppl can think alcohol even tho 40% are alchohics another 40% are crackheads and the remaining present is other; stereotypically speaking.
