Conversation day 1

Today is September 8, 2020. I continue to learn English with my partners. Here is our conversion that we talked:

me: Can we make a voice call?
she: Sorry I am working right now and I don't think I'll be free to talk today before you go to sleep.

me: It's okay, You are a workaholic person.
she: I'm not.I'm actually a very lazy person, it just so happens my work hours plus the time difference means when u ask if I can talk, I'm busy. and I'm very free after 6 pm until midnight, but you would be asleep then.

me: This is a great example, perfect sentences, you know I love it but I don't understand "plus the time difference means when u ask if I can talk I'm busy", "I'm busy" is a complete sentence why it is at the end of the sentence without a comma before it.

she: My bad, sorry. When I text I leave out most of my pronunciation. Most people do. You usually just know where the commas would go.
me: I see, to save time.

me: What's the meaning of the word 'aeoerste', I just searched it but get nothing.
she: Same. I have no idea what it means and when I searched it up nothing came up as well.

me: Today I learned how to link words together, and I get a few issues to ask.
she: I'm going to be brutally honest. I don't understand why this is a rule. You can read all of them as it is. Sometimes I slur my words together in an informal setting or I'm feeling lazy(easy).

me: What the meaning of brutally?
she: I'm going to be very honest. Same meaning, I will say it as it is, even if it may not sound nice or make you feel good.

me: When do you go back to school?
she: I move into university 27 Sep.
me: You're starting university soon.

me: How many hours do u do work a day?
she: 5 on the days I work.

me: I just searched it in the dictionary and there was no explanation like you said, so it made me confused.
she: Just say it, "Just saying" = kind of informal speech by itself. Meaning = I'm just saying it in this way. But has an informal tone to it, and can be rude if you say it in a rude way.

me: You said a lot of good sentences that I have never seen before. It can help me a lot if you talk with me often. I guess my writing will improve/get better.

me: I read your messages many times. It is just so interesting to me. I can learn a lot from them.
