Unsolicited Advice

Have you ever had a time when people think they know so much about what you are going through and they empathize or even sympathize with you?  Have you ever had a time when the more wise and experienced give you advice in which their parents or elders gave them?  What about a time when someone gives you random advice?  I welcome advice and even constructive criticism, but my recent pet peeve has become unsolicited advice.

So I'm new to the whole pregnancy and motherhood thing.  Every new mother is.  I often worry about the things I don't know, and as I told my mom, I'm going to look at this go round as a "trial-and-error" thing.  You never know until you try, right?  Recently, I have come across people who give their opinion on EVERYTHING I say, eat, sit, walk, dress, or do while I am pregnant.  I know that I am carrying precious cargo.  I know my limits.  I know how I feel.  I know what I really shouldn't do.  I get so aggravated when people tell me something over and over, or give their opinion when I really don't want it.  Being pregnant has definitely taught me to be patient, but my patience is running thin on people giving advice when they should keep it to themselves.  I know the right thing to do is be benevolent or amiable and smile, but my fake smiles and fake benevolence is running out.  If I want your opinion, I will ask, otherwise, keep it to yourself!
