Hey......,

Are you free next Saturday afternoon?

I'm going skateboarding with my sisters. Do you want to come?

We can meet at 4p.m. I think you really like it because it should be lots of fun. It cost 50 thousand dong to rent the safety equipment.

Let me know by Friday if you want to come.

See you later,
