By 'socially skilled' do you mean the ability to foresee and avoid social blunders, and also being able to read a situation to figure out what is appropriate? If so, then I am not all that great. If I am excited about a subject, I have a tendency to cut people off. If I smoke socially it is easier due to the pause between exhales. As an introvert I also have a tendency to fall off the map, even if I am active during social encounters. Thankfully I get stir-crazy, but I rarely feel a strong desire to just be with someone, especially outside of my circle of friends.
I also struggle with knowing what might be awkward for others, since I can be comfortable talking about anything.
One issue is that it is very hard to tell what the most appropriate path is, and usually the safest route is the one of politeness, which is not how I hide myself. I hide myself behind banter, which does not work in all situations.
My strength? The ability to live and let live. I identify as an enneagram 9 after all (which seems to be common among male INFJs on this forum)
