To play devils advocate here:

Nobody can tell the age difference between an 18-year-old and a 16-year-old without seeing proper identification. It is an impossible task and you are lying if you are 100% certain otherwise.

If you are walking down the street and see 3 girls walking and talking together on a summer afternoon. You don't know these girls. They are all strangers. They are apparently teenagers. You can't tell if they are 14 or 20 just by looking at them. You can't tell there age by having a conversation with them. You have NO IDEA how old they are until and unless they show an ID.

Some 20 year olds look and act 14.

Some 14 year olds look and act 20.

16 and 18 makes sense but 14 and 20 is a big ass stretch
