Yes, these 2 words really do have the magic.
It was that one day, I was really stressed out by all the assignments and then a person came up to me and asked me for help. Being the "ga enakan (can't say no)" person, I agreed to help.
And that moment, when the person said "Thank You" to me, suddenly all the burden was lifted up, it changed my mood and all the stress was gone. I didn't know a simple thank you can do much until that day.
