Be yourself, make your own path. If you want to present female at Xmas and respect your parents wishes, drop some emails or make some calls or even do it on FB then do as you wish. I wouldn't get too hung up on passing the full time test or failing because of five minutes out. I am sure any decent therapist can reconcile that. If I pop to the shop first thing in the morning without my wig...am I breaking the rules. If I am selectively presenting male to not cause shock or distract attention from the event I attend, I am just being diplomatic at a cost to myself ... not failing full time. Good luck!
