When Danny brings Sweet Talk to enroll him in rehab, the clerk expresses uncertainty that he will be able to get in that day because they're short of beds. Yet, when a young girl comes in right after, she is told that the bus will be picking her up to bring her to rehab in 20 minutes.
If the childhood friends are 30 years old, it seemed odd that none of their parents were mentioned or seen. It's a stretch to say that all of them are dead (they'd be in their late 50s or somewhere in their 60s) at such young ages, but yet they're too old to be retired and moved south. Danny even still lives in his childhood apartment, but there's no mention of what happened to his parents.
