I know the more I get closer to someone emotionally the more little things will annoy me.. maybe your intimacy is building and the annoyance is a defence mechanism to getting closer.. I ONLY say this because I felt it myself.. my T started annoying me over stupid reasons. I love him, best T ever... but little things really bugging me. Then I would think of his care, help and wisdom and I would be ok.. and thankful to have him totally get it though!
