first I told you they laugh at you means they laugh secretly not appearently second be sure if your basic structures will incorrect but your idioms not they'll laugh and suprise
yes both of us are a little in hurry the first step for english learners aren't speaking and learning idioms
in spite of this they are common in some english insitutes. as a matter of fact both of them are effective in the
new method of english learning but idioms are taught in intermediate level and
speaking is taught from begining
and the reason I suggested so because I foud out that the most users of this community are in intermediate level of english the same as me
Goodness knows
anyway I enjoyed this discussion
Good luck
