Is it weird to urinate in your garden?

I'm having a debate with my friends. We have 1 toilet in our house. If it's busy, is it weird if I wee in the bushes in my garden? I don't think its weird but some of my female friends do.

Edit: A lot of people asking about the conditions for me to pee. Firstly, it's very rarely. It's normally when I'm drunk and dark outside, and always ensuring I can't be seen by anyone.

I know a lot of you say it's weird but I don't see how it's any different to doing one on a hike or when really desperate. Sometime, if you've gotta go, you've gotta go.
