Today I went to the mall with a group of friends. Actually, I didn't go there to buy anything I went window-shopping. It is always a good thing to hang out with friends. We were 4 girls and all of us had ice cream. The other day I and the same girls went to the beach just for a walk; we didn't swim in the sea. Walking is good as well, there is a perfect sidewalk for the pedestrians, and it is an appropriate place to spend my spare time. When there is nobody to hang out with, I just go out by myself and it is not that bad, sometimes I run into someone I know and it turns out I am accompanied.
How to use actually in a sentence:http://sentence.yourdictionary.com/actually
Some important points to highlight:
If you are telling a story that happened in the past, you should pay attention to verb forms. The verbs need to be in the past form. Don’t use the present simple e.g We have ice cream (wrong)
Be careful wiht the spelling. e.g by (buy)
If you want to say: The walking was good. (it was not wrong) but in the sentence you wanted to say that (caminhar também é bom). So, you should use Walking. Because if you wanted to say:
A caminhada foi boa. Then you should have used: The walking was good. In my understanding, you wanted to say that walking is as good as swimming in the sea. Unless my understanding was unfruitful and poorly productive. I’m genuinely concerned that I didn’t get what you said above. Please, correct me if I didn’t get what you were trying to say.
Spend the spare time – use spend + possessive adjective pronoun+ spare time. In this particular case, it sounds more natural if you write with a personal tone. You wrote an informal text. You are talking about yourself and your dearly friends.
If you are hanging out with a pair of friends it means two friends.
Or if you are hanging out with a couple of friends it means two friends.
I have slightly changed the order of some sentences in order to keep them more cohesive.
Congratulations on your text. It was a lovely one. Keep writing.
