Hi Jo,

How are things? I've got some great news! Keira and I will definitely visit our

grandparents in July. We will

certainly stay for three weeks, and maybe longer if we can. Will you be

there in July? I hope so! My dad

definitely won't come with us because he's working, but Mum won't have to work all of July and so maybe she can join us later.

The other news is that I might have a party for my birthday. Dad has said yes but Mum hasn't decided yet. It's OK, I think she will probably agree soon! If I do have one, can you come? You can stay the weekend.

Please say yes! It won't certainly be

the same without you!

Gina
