In the last two years I've been mainly programing with C# at work and Ruby ( Rails and experimenting with Hanami) @ home. Soon I`m changing the job and will again work with PHP with which I have 7 years of prior experience.
I consider myself language agnostic and as Edouard said there is always something to learn from the other languages. For me it's always nice to tinker with some different languages, technologies and frameworks.
