don't do it. it is rude AF. no one wants a call or text at 4 am. IF you want to book a woman awake in the middle of night, arrange it in advance and don't be contacting random women out of desperation at 4 am. That is why I have hours on my ads, every ad everywhere. I just block the middle of night guys because if they are that rude and thoughtless, we are not a good match. It amazes me how many guys do this. if any woman likes this time to work, make it known and advertise that so these night owls will leave the rest of us alone. Also, how can anyone even check references at night?
