I think many people don't think before they talk because their parents didn't teach them what to do when meeting new people. In my house, I practice communicating situations with my 7-year old daughter. "If we see this, we say this . . . " Then she parrots me. I can't prepare her for everything, and let's face it, I blow it a lot myself and I'm very sensitive about asking certain questions or saying certain things.
People also don't think before they talk because they may not empathetic to others' feelings or are simply ignorant of a situation. For example, I teach a lot of people about communicating when they meet someone new based on my 7 years experience of infertility and two miscarriages after a successful pregnancy.
One thing I never ask someone is, "Do you have children?" If they tell me about their kids, great. If not, it may be because they couldn't have them or there were miscarriages or even a death in the family. I hated answering this question during the seven years it took me to get pregnant and I don't ask it of anyone, ever.
Before I had our daughter I would get asked, "Have you ever thought of adoption?" I would think, "Only 1000 times." I would answer, "Adoption does not cure infertility." I would have loved to adopt a child, but some women want to experience pregnancy and asking this question is insensitive. Infertility is a unique situation to grieve because you have no closure and asking about adoption should be done with great care.
When I meet new people now, I get asked a lot, "So you only have one child?" Like one isn't a blessing or like I'm a selfish person who is depriving my daughter of a sibling. I say, "I've been pregnant 3 times and we have one beautiful daughter. I'm looking forward to meeting the other two when I get to heaven." This makes people pause and I hope stops them from asking that question again.
Thanks for sharing your experiences to remind us or even enlighten us on a more positive way to communicate when we meet someone new - whether they look different from us or not.
