could you please tell me what is the rules for writting to a new penpal
Hi there Hany,
I'm not sure there are any rules as such.
I'd suggest that you could write to them as if they are friends, ie: using a fairly informal tone. Of course, being a new penpal you might want to be a little cautious about giving out any personal information.
Here's a page I found that gives some basic advice...
I hope it helps.
I'm not a teacher, so please consider any advice I give in that context.
