Hi Everyone 
This is slightly pathetic I almost feel embarrassed writing it! Slight issue at work and I am not sure how to proceed.
In my office there are 3 of us, myself, my manager and my colleague who we'll call J.
J was off all of last week, and my manager was also away on business. So just me in the office - I am fairly new to the role (less than 3 months) so I was stressing slightly about having to deal with everything by myself.
On our factory floor there is a lady 'M' who is generally known as the workplace gossip. M asked me last week how I was getting on, and I said I was having a bit of trouble as customers had called through orders on the telephone from the week before - and their order hadn't been written out. It is quite an old fashioned business, we only communicate with our customers via the phone and not email. When speaking to M I did not mention any names about anyone, as I was aware it could have been any of the other 2 people in my office who didn't pass on the info.
J has returned to the office today, and has told me that M has told him to 'be wary of me' and that I have been being nasty about him all week. Although M was off sick (funny that when the manager is away) for 3 days out of the week, and my manager was back on Friday - so I was on my own with her for ONE day.
I have apologised to J and explained that although what I said wasn't directed at him, I asked could he take more care in writing down information - which he has admitted he doesn't do. I am not sure he is too happy with me though... 
My question is, how would you go about this?
I am only 20 and in a fairly good role for my age, so I dont want to go crying to my manager looking like a child! However, if he was to find out I would prefer he heard it from me.
With regards to M, I think I will no longer engage in polite conversation with her like usual (i.e. asking about her weekend/grandchildren) and just keep all conversations strictly to work. Or should I say something to her? She has worked in the company for at least 15 years so although everyone knows shes a massive gossip what shes like, she is part of the furniture.
If you have got this far and are having a day boring enough to invest in something so pathetic.. please help me
