Can I always use wanted in the following sentences to show politeness? and will it cause confusion to the listener as they may think that I've changed my mind before saying to them? or if I speak in the present time I should only use want?
Here are the sentences:
- I just wanted you to know that I was appreciated your help last night
- I just wanted to say thank you
- I just wanted to let you know......
- I just wanted to invite him over: Like this one that I mean in the question. Does this mean the speaker has changed their mind? or it's acceptable to say just to show politeness when he/she wants him to come over? but will it cause confusion if someone says it?
