It's really complicated in a relationship especially with those who speark a different language as their mother tounge. English is suppose to be the most commonly used in M'sia but cause of the slang and the way they speak, sometimes... No.. I should say most of the time it makes the other person gets confuse and then misunderstanding happens there.. Or I should say it's a miscommunication? Dam!!! Tough life!!! Sometimes having arguement cause of small stuff is kind of fun as it will sparkles up some fires in between.. But it's long, you'll feel bored with it and hope it will end asap!
