Hahaha don't worry about estimating people's ages. I'm 20 but when people look at me they always think I'm younger. The same with my brother, people always think he is older, one guy thought that my sister (13 at the time) was my brother's (17 at the time) daughter.
woah your sister being mistaken for your brother’s daughter…
sounds like song lyrics ahaha
yeah I guess looks really can be deceiving huh
