Flirtation is a wonderful way to bring a smile to another Heart and Soul. Yet there are people that then see it as you are coming on to them when it is the farthest thing from the truth. May be it is there partner that takes offence or they know there partner will. Or it good be you just need to ask this friend to stop because you feel uncomfortable. Tell them straight up before you end what could be a wonderful friendship. May God bless all.
