If a 30-year-old woman looks like she’s 18, don’t talk to her like a 18-year-old girl. I don’t know what is incomprehensible here.
= = = is = is = is = is = is = is = is

It seems to me that neither a 30-year-old woman nor an 18-year-old girl should be talked to anyone like an 18-year-old girl. Normal people actually do that. Surprised by?
