1. "I am happy with my brother." - This sentence means that you are happy when you are with your brother. It implies that your brother contributes to your happiness, but it does not necessarily mean that your happiness is solely dependent on your brother.

2. "I am happy for my brother." - This sentence means that you are happy on behalf of your brother. It signifies that you feel joy or satisfaction regarding something positive that has happened to your brother. It does not necessarily imply that your happiness is directly influenced by your brother's presence.

3. "I am happy because of my brother." - This sentence implies that your brother is the reason behind your happiness. It suggests that your brother has directly or indirectly contributed to your feelings of happiness.

4. "I am satisfied with my brother." - This sentence indicates that you are content or pleased with your brother. It generally conveys a sense of approval or fulfillment regarding your relationship with your brother.

Regarding the differences between the sentences, #1 and #4 have similar meanings, as both express a level of contentment or happiness related to your brother. However, #1 specifically focuses on being happy when you are with your brother, whereas #4 conveys a more general satisfaction with your brother.

If #1 is interpreted as meaning #4, it could be because both sentences express positive feelings towards your brother. However, it is essential to consider the specific context in which each sentence is used to accurately determine their intended meanings.

#3 is the sentence closest in meaning to #1 because both emphasize the connection between your brother and your happiness. However, #3 implies a stronger causality, suggesting that your brother is directly responsible for your happiness.
