I knew my gf was closed off with things.she didn’t like too talk a lot unless you genuinely knew her.She didn’t like sharing things about herself that was upsetting her because she hated bothering people and thought they would hate her.She hates telling things that she has achieved or done that makes people think she’s good at stuff because she hated bragging and hates getting praise,though she actually loves it.But what happens in her mind stays on her mind,that’s her rule though I hate it
