Sweet - Experience
Romantic - State/mood
Flirt - Activity
I like your question. It is a very good question.
You want to have a relationship with the first two but only play with the third?
people who are sweet make good friends,ppl who are romantic make good partners and flirts come in handy when those sweet n romantic people leave us...
a flirt can be sweet and romantic...
a romantic can be flirt and sweet...
but a sweet can be romantic and not flirt lol!
If we knew that it wouldn't be as much fun.
