Well, it will sound silly now but our first conversation was about Jainism and I just found it really interesting. It moved onto him talking about being a botanist and naturalist and his passion just shone through and hooked me in.
He is also really bloody genuinely lovely- he is kind, passionate, sensitive, loving, polite, funny, clever and he made me feel (and still does) really special and beautiful.
The second I spoke to him I knew I needed him in my life in some way. By the third date I knew I needed to marry him. Ten years later and I would do it all over again.
