It's my first time posting here so just bear with me.
I work at a software development company that primarily focuses on C#-based web development, but they also work on desktop applications on occasion. I began interning at the company last summer, roughly 8 months after a good friend of mine started. After the summer ended, I became a near full-time employee. From there up until a few weeks ago, I handled tasks like solving platform compatibility issues, database maintenance and Amazon Web Services. I have a strong background in C/C++ coding, as well as assembly and a few other languages. Recently, my boss has decided to try and get me up to speed with C# Web Development, as our company is taking on a large project. I am totally open to my boss trying to teach me new things, but my willingness to learn appears to be provoking some negative comments in the workplace (mind you, we are a company of about 20 people.)
Typically, my boss will assign me a task, and leave me to figure it out. But within the past few days of training, he has been sitting directly next to me, watching my every move. I, unfortunately, don't exactly work well when my boss is sitting inches away. I end up asking stupid questions that I do actually know the answer to, but I am so flustered that I simply can't give a proper response. Try to keep in mind that this code training has been underway for only about 3 days total. Everything was going just fine, up until this past Friday. I asked a valid question, only for my boss to turn over to a co-worker and say "See, this is how [Friend] was 12 months ago. You can really see the growth with [Friend].." I simply ignored the comment as the two exchanged a laugh. Later in the afternoon, the same co-worker went to help our graphic designer when the boss was out to lunch. I overheard him say "Wow, you are almost worse than [Me] at coding.. that's sad". He then proceeds to glare over in my direction.
So I guess my question for all of you is how can I deal with the negative feedback? I am a quick learner, but I never expected to get mocked for not learning an entire language with all it's nuances in 3 days flat. Am I just overreacting? I appreciate any comments.
