My girlfriend and I always hold hands and discharge. What happened?

This is caused by cold and dry weather. I don't think it has much to do with charging, nor is it tip discharge, but some static electricity. I have never held hands with my sweetheart. Maybe you and your girlfriend are not ordinary people-I sincerely wish you a long life together. If it takes too much electricity, put some hand cream or something before holding hands next time. You can also wear gloves.
