Adults who have themselves grown up bilingual, however, generally report when asked that they never had problems knowing what groups they were a part of. Some even find this concern to be rather bizarre. Children who feel accepted by both their cultures will identify with both. Unfortunately it happens that two cultures have such unfriendly relations that a child who should belong to both is instead shunned by both. This is not however a specifically bilingual issue.
Bilinguals have to translate from their weaker to their stronger language.
The overwhelming majority of bilinguals can think in either of their two languages. They do not, as some monolinguals assume, think in one language only and immediately translate into the other language when necessary. Children who grow up bilingual will make great translators when they grow up. By no means all bilinguals are good at translating. Nor have any studies shown that growing up bilingual gives one an advantage or a disadvantage over those who became bilingual as adults when it comes to translating.
