Get Laid Tips

My friends mother has been flirting with me for a number of months now, and up until now i’ve been quite reluctant to flirt back. She has started getting more and more open with it however, and i find myself being strangely attracted to her in quite a strong way. Is this weird? If it isn’t, does anyone have any tips on flirting with older woman, around 35 – 40 mark because i really do like her a lot, and whether its just a crush i think it could still be fun.
