I’m still not sure I understand the problem, can you be more specific?
assitant
But your house wouldn’t be painted a long time ago, because lead paint wasn’t used at that time.
assistant
Gosh that would be terrible.
user
What would be terrible?
assistant
To find out your house has lead paint.
user
I don’t think there’s any lead in the paint anymore.  Do you know about this?
assistant
Yeah, but what if your house was painted a long time ago?
