The alarming thing about ladies I’ve found, is that they’re often different to each other. So while some of them like cats and you can lie and pretend you like cats to those ones, obviously lying to ones who don’t like cats will make you less desirable.
In the long run, if you lie that you like cats, and end up living with said lady, you’ll probably end up sharing the house with some of the fetid, self-centred evil ones which will just end in tears.
So it’s probably best to just be yourself, be relaxed and don’t try to be anything you’re not. Try not to think about nailing her too. That can lead to a funny look in your eye and will often encourage you to take some risks that wouldn’t normally fall into your nature. Imagine you’re taking bob from engineering out because you like him and nothing more.
