Hi, Lee,
Guess what! Sabrina and I are going to see (see) a concert next month! I'm not sure if I will go (go) with her, but I am going to buy (buy) a ticket, so I might see her there. I know the concert is popular, so I am going to buy (buy) it soon.
Sabrina is going to study (study) hard for her exams next week – she thinks she will pass (pass) them easily.
I am going to meet (meet) her after the exams – but I am not going to celebrate (not celebrate) with her because I have other plans.
See you soon,
Abigail
