What is the difference between zobaczylismy and widzielismy
I know someone will give you a better answer, but I think one is saw as in a passing glance (zobaczyć) the other is saw you as in more than a passing glance (widzieć).
Thank You! Dziękuję
Czemu nie: Widziałyśmy Pana w restauracji?

What is the difference between 'zobaczyłyśmy' and 'zobaczyliśmy'?
In "zobaczyłyśmy", 'we' are women only. In "zobaczyliśmy", 'we' are either men only or a mixed group.
