Random vocabulary exercises Hi, I created some sentences with words that I am memorizing. I would appreciate it if you could make a correction or give me a tip. 1.

Even though peole give me advice, it is meaningless, so I bypass it. 5. I especially get along with two of my friends. One day, when they argued each other, I meddled in ther argument. Thank you
