Vaccine roll out.

Send your Mum a card now, to show you're thinking of her - don't wait until her birthday.

VC is absolutely right.
My brother in Yorkshire and my sister in the States regularly send my mum flowers and a little note. It lets her know she is always in their thoughts, and lifts her spirits no end.  Her two granddaughters (in their forties) also occasionally send  their grandmother a chatty card telling her what they are doing and how their families are, which I read to her. As she is hard of hearing and has almost no vision now, chatting over tinterweb is not possible, so she loves to get written cards.
