As others told you, you can't and you are not allowed to do that.

If your frien only needs Acrobat, your friend can take an Acrobat license. That's more economical. Depending on the need, you have different options. 

A Teams license as suggested by @Nancy OShea is only interesting if you are a company. Individuals are better off with the classic subscription (for a year or a month, whatever fits your needs). 

Short answer:  You can't.   Your "friend" must get their own license.

Adobe Terms of Use: https://www.adobe.com/legal/terms.html

Individual license is for 1 user only.  However, you may install and activate apps on up to two devices concurrently.  For example: work/home, desktop/laptop.  But you may not use more than one device at the same time.

For multi-users, see Teams/Enterprise plans for businesses below.

Hope that helps.

if you have an individual plan, read the above posts.

the other plans include a control panel can allow multiple users and enable application restrictions.

Cloud License allows 2 activations at a time http://www.adobe.com/legal/licenses-terms.html
-you may use on ONE computer at a time, and you may NOT share your subscription

There is no 2 user registration, just 2 computers. You MUST NOT allow someone else to use your account, at all. No part of the account is to be shared. The 2 computer limit must be for computers that only you can use.
