What should I do, I went to the wrong toilet, everyone helped

Wait until no one leaves, but it is even worse to be found. Otherwise, ask the next door directly: Sister, did you go to the wrong toilet or did I go to the wrong toilet?

Then you should be asking questions on your mobile phone at this time, but why doesn't it show that you "know from your phone"? Generally, it is not displayed and the question is asked from the computer. If it is true, then you should listen to the sound smartly, and when you think you can come out, you should quickly lower your head and walk out quickly (I think running will increase the likelihood that others will look the other way, and others will think about it), and you must walk quickly to the men's bathroom, this act is to show that you have gone to the wrong toilet and not for something else.

If you meet a woman when you come out, you must fold your hands and cover your face and say, "I'm sorry, I'm sorry, I made a mistake, I thought it was the men's toilet, I drank too much", and quickly walked to the men's toilet while explaining, and walked out as if nothing was fine after recovering in the men's room.

You just have to be patient and wait until no one is around before going out. Or just go out and leave quickly.

Cover your face, take advantage of no one, and run quickly.

Be calm and tell yourself that this woman went to the wrong toilet and go out calmly and wash her hands and be calm.

Wait for the girl to go out before leaving, or call the girl for help.

Just go out and relax, boy! If you are calm, others will not notice you.
