Hello!
I have to disagree with krkoza. Her advice in this case is not helpful.
In the US, we say...
She is exciting = She is an exciting person = She does things that excite other people.
For example: She rides in rodeos or bungee-jumps off bridges, and we all love to watch her in action.
She is interesting = She is an interesting person = She does things that interest other people, or that they want her to talk to them about.
For example: She is an expert in many fields: Ballroom dancing, international relations, fine art and gambling.
Of course, a person can be both exciting and interesting.
For the noun "tension" we use the adjectives "tense," "intense," "anxious" or "tight". It all depends on the context. Could you provide more specific information, so we can help you?
Instead of "wait from you" at the end of a message or letter, we say...
"I �m waiting to hear from you" or
"I look forward to hearing from you" or
"I eagerly await your reply."
