this is not coding style we use.
Also we can limit the scope of w to the loop.
I also do not really like these kind of one letter variables unless they are used as iterators. So you better use written here or sent in case you actually want to use send() and not write().

The variable name t is also unclear to me. What does it stand for.

We do not use this coding style.
