My teachers assistant (TA) gave me his number?

Anonymous
I emailed my TA of how he did a good job of helping us learn the course material out professor taught us, and I wished him good luck in his future. At the end of the email, he included his cell phone number and his email address. Is this normal? I've seen mass emails he's sent to the whole class, and he didn't include his number.
