I wish I could say it was for a girlfriend, but actually I'm going to be saying it to my Mum at my 21st. It's hard enough to say in front of a big crowd in English, so I thought I'd do it in Finnish to make it more meaningful for her and also to save me from the ribbing I'd get from my mates
But ssshhh, just keep it between us, ok
Thanks for all your help!
