this afternoon I got the feeling someone was going to collapse

I was talking to someone who had a really bad cold, and she suddenly went all quiet for a bit (then started muttering something about eye lashes), but in a way that suggested she wasn't too sure what she meant to say or what she even was saying- and I know that could be signs of a collapse

but before I could say something and ask her if she was okay she noticed me looking at her and coughed and said she needed air

I'm still thinking about it now

collapses scare me

not if I collapse, if other people collapse
