@SheilaKathy who said, "Well, since you and I are both of the same faith, I think I shall quote the Bible verse in my thoughts on this subject..."
I think it is important to note that the bawdy stories, jokes were within ear shot of you but were not directed at or to you at least not that you described above. It is unfortunate that you were seated and stuck in that situation for the duration of the trip. But whether you choose offense or not is up to you.
I have worked in an all male field in the military, my own father was notorious for his heavily sexualized jokes, stories and comments (which totally embarrassed, upset and morified me), and I have worked with many male elderly who aren't appropriate by todays standards but who were risqué. I was often picked to care for those difficult ones because of the number of women CNAs, HHAs, Hospice Aids or agency caregivers who chose offense. To me, though it can make me uncomfortable, it is just "guy talk" unless it is a direct comment or joke of a sexual nature to or about me.
Biblically -To me, it is better to embrace patience and longsuffering rather cultivate being offended. (Galatians 5:22, "But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness") Longsuffering/Patient endurance. God has been patient with us and we are to be patient with others (1 Thessalonians 5:14: "We urge you, brethren, admonish the unruly, encourage the fainthearted, help the weak, be patient with everyone.")
Further we are to be in the world but not of it... and we are called to "Be wise in the way you act toward outsiders; make the most of every opportunity. Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone," Col. 4:5-6(NIV).
Your question was: Would this kind of thing have upset you too, or am I just too sensitive?
To which I answered no. As to whether or not you are "just too sensitive" - I didn't even go there, however by your reply to me it suggests yes.
