My friends and me

I invited my friends to my home. Maybe they will come in this week, I am happy for accepting my invitation.

I will make arabic coffee with dates as normal situation when the guest come.

Then I will buy some chocolates and snacks as mini sandwiches. If I have a time, I will prepare some gifts for them.

Now I wanna rewrite what I was wrote in the past:
Last week, I have invited my frinds to my home and they came at 8:00 p.m, in the last week.
I made arabic coffee with dates and some snacks

I gave them a small gifts. Really, it was an amazing day.

 

后顾之忧 -> Fears :)

I noticed something bad so could you help in "whatever your want", please?
