Linda smells bad!
Patricia smells the flower.
When you say the first sentence, the one who sniffs the scent would be the others than Linda herself. On the other hand, on second phrase, the one who is sniffing the flower is obviously Patricia.
Then here I'm curious that when natives hear the speakers say up until the moment right after the smells,
Linda smells....
Patricia smells....
how would they think which is the one who's sniffing right now? Do natives think the verbs in "smells bad" and "smells the flower" two different things?
