Been there done that with the wax. Peeling my undies off for ages! It took so long to get rid of the wax. Definitely don’t do that.
Don’t try out a new hairstyle, skincare regime or anything apt to leave you looking your worst when it doesn’t work out.
Don’t go rollerskating, surfing, skateboarding or anything like that unless you’re an expert. Almost certainly you will fall off and have to meet your date wearing a sling or at best, covered in bruises.
Don’t talk too much or too fast. I do this when I’m nervous. One guy I dated told his friend after he met me ‘I hope she doesn’t talk that much all the time’. He was taken enough to overlook my motor mouth action and I don’t talk that much normally. We ended up dating for ages.
Do read the newspaper and have a good idea about the current affairs of the moment. You don’t want to look like an idiot.
Perhaps suggest a film so you have something to talk about afterwards in case he is shy (we know you aren’t).
Wear something where it won’t matter too much if you do spill a bit of coffee or something down your front.
Let a friend know where you will be if you don’t know this person well.
Have an exit plan in place in case you really need to get away.
