What does "흔적남기셨길래 찾아왔습니다" mean?
Someone mentioned me on twitter "흔적남기셨길래 찾아왔습니다" and I don't understand what he/she is saying. I tried using google translate but it says "i left the trail" which doesn't make sense to me. Please help me. Thank you ^^

thank you ^^

Answer

It means "I replied because you left a comment (at my twitter)." 
흔적 literally means "trail" but also means "trace" (which remains the result of someone's act such as comment or staying too).
