Some keep contact with their friends via Internet; some send letters and postcards, or even photos; others may just call and say hi, just to let their friends know that they're still alive and well.

有些人通过互联网跟朋友联络；有些人寄信、明信片，甚至照片；还有些人可能只是打个电话问声好，目的仅是让朋友们知道他们还活着，而且活得不错。

If it's because they're just different and maybe they come from a different background than you, then no, your friends shouldn't have any say in that.

假如只是因为他们性格不同，来自不同的地方，那就不是问题，就算是自己的朋友，也不应该对此有意见。
