Hi Bob,

Thanks a lot for your message. I'm glad to hear from you again!

Well, the last time I [felt|feeled] ill was a month ago. I had [a|the] terrible toothache and even had to go to [a|the] dentist! Honestly, I seldom visit doctors because they're a bit scary, but that time I [couldn't|can't] go without the [dentist|dentist's] help. Now I understand very [well|good] that it's very important to take care [for|of] your teeth and health in general. That's because health is necessary if you want to live [the|a] long and happy life.

Sorry, I'd [better|best] go now as I need to do my homework.

[Drop|Throw] me a line when you can.

Best,

Eugene
