Since I learned about the history of the Korean languege, it doesn't sounds wierd anymore and I felt that I should respect other countries' langueges as well!
Korean people like kimchi so much that there is even the song that has the lyrics 'I can't live without kimchi' and 90% of Koreans agree with that lyrics.
If you are greeting with the person who has the similar ages compared to your ages, you just say hi or just wave ur hands to each other
Now, you know why Korean people like kimchi and how meaning kimch is for Koreans, you should respect what we eat and respect what other countries' people eat as well because what they eat is meaningful for them and have the reason why they like that food.
Since, Korean people starts eating when they are young, some koreans eat kimchi with everything even with pizza, pasta or hamburger.
