I once went to a book study group that was held in an MS's house. There were just a few brothers there so I couldn't slack and get away with it, I had to do the prayers, reading and answering up.
Now my accent wasn't local to this group, in fact it was pretty strange and I already had something of a complex about having it. To make matters worse the MS had a teenage daughter (17) and every time I opened my mouth at the study she would giggle. This went on for weeks and no one said anything because it was her dads house. I'd put my hand up to answer, I'd say just one word and then there would be a giggle and I would become very aware of my accent and that I was being laughed at and that would throw me off what I was going to say causing me to be further embarrassed. It was really cheesing me off because I thought she was taking the piss. Eventually I stopped answering up and taking part. This was noticed by the elder who questioned me about it on service one day. When I explained I thought I was being ridiculed he explained to me that it was nothing of the sort. The real reason she giggled was because she had a crush on me, she couldn't help herself even though she'd been spoken to about it by several sisters.
I then had to put up with the giggling until I was moved by the PO
