I think it was last week (or two weeks ago?) when I threw off my "winter coat" and went swimming. Quite late for me, as previously I've done it in May! Once you start swimming and eating ice cream outside, it really starts to feel like summer. And we also take our summer cutlery out and have lunch out in the garden. And all the nice things! Do you have something that you have to do before it really starts to feel like summer?
