Its perfectly normal to worry about a loved one when they are traveling! Bet your mom is smart and tough though and will be just fine
Im 30 and worry about my mom still... but when she does do something I still look up to her and know in my head that if she can do it I can too!!! Im flying alone for the first time in my life in Dec. Im scared that I wont get it... Im scared I'll miss my connecting flight, that I wont find my gate, etc...
What makes me feel more comfortable is that my mom flew here from New Mexico (same flight Im taking) by herself twice now! If she can do it, then I can too!!!
mother/daughter relationships are special!!
