I've just put mine in the oven.
I think the last time someone made me a cake for my actual birthday was a friend about 10 years ago as we happened to be meeting up with the kids that day. I was so pleased, wasn't expecting it at all.
And MIL will bake a cake at the drop of a hat, so I've probably had cake off her too, although not on the actual date and it tends to be a bit random as to whether she's remembered it's my birthday or she just fancied baking cake.
My mum would bake me a cake if she were still alive and we happened to be together (I live abroad).
And so I am once again baking my own birthday cake for tomorrow, and it's made me a bit thoughtful and a bit nostalgic and, if I'm honest, a little bit sad too.
