be a professional and don't react this will give you alot of practice on tolerance for the rest of your vocational endeavors I realize it bugs you and if they are regulars or friends of the fam then you might could say in the most cordial way that it's not like that and that you enjoy helping your fam out, something that doesn't reflect your anger
I think it's quite admirable, not many teens willing to work at 18 let alone 14. know that what your doing will give you good work ethics which are rarley found in todays younger working society and will carry through in whatever you do. Koodos to you! You are gaining skills that will help you get and keep whatever job you aspire to get!!!!!!!!!!!!!!!!!!!!!
and leave others lacking in the dust
